It’s like the periodic table: you have different kinds of quarks, though only two form most of the baryonic matter (anything that’s not dark matter or dark energy): up and down. There are also leptons, which are electrons, it’s two heavier cousins that disintegrate quickly (muons and taus) and neutrinos (which are very light particles required for conservation of momentum). Finally, bosons are force carriers: they are what let particles interact with each other, and carry the 4 fundamental interactions: strong nuclear force (gluon), weak nuclear force (W and Z bosons), electromagnetic (the good ol’ photon) and gravitational (graviton, still hypotethical), plus the Higgs boson which gives mass to other particles.
Those specific wavelengths of light that atoms give off when being energized is how narrowband astrophotgraphy imaging is possible. High quality filters allow us to block out everything but that specific wavelength (hydrogen-alpha, oxygenIII and sulfur II), and provides some really awesome, high contrast images.
B&K Science and Astronomy Nice. Thanks assh*le. This sounds so interesting now I will have to dig into this topic. I know about Fraunhofer lines but nothing about narrowband astrophotography. This will keep me busy quite some time. Thanks again!

In fairness, they’re going to immensely improve all lighting systems, from decorative and general home lighting, to displays, cameras, and medical imaging. Quantum dots are the light equivalent to, say, graphene or carbon nanotubes in terms of their potential impact to our day-to-day lives.
Keld Tundraking they’ve been in mainstream market TVs for about 5 years now, and every roadmap going forward uses them in every emerging display technology, from current transmissive QLEDs, to QD-OLED (if it ever gets off the ground before the better stuff get going), to microLED, to EL-QLED.
@@TenMillionYearProgram42 We'll see how mainstream they are when they're not using antiquated transmission display. Going whole hog on color depth and then turning around and ditching HDR is silly. A standard OLED already looks amazing, has great HDR and doesn't have to add yet another material to mine, process, and manufacture. Anyone who went out and bought one of these things cause it had quantum in the name despite using the same backlit tech my $100 monitor uses is just buying pricey toys, not chasing the sensible evolution of tech.
Well, actually: joking aside, not everything in the universe is made of atoms! For example, energy is made of photons instead of atoms. And then there are things like neutrinos. And there could be a whole zoo of particles smaller than atoms, that we haven't discovered yet, including possibly string-like-matter (if String Theory is actually true). And as for Dark-Matter--WTF is that made of!? Further, there is a tangible form of energy we only recently measured a few years ago, known as gravitational waves, which is made from the space-time fabric continuum (whatever that is!). And then there is time itself... time and temporal phenomena exists... but what is that made of?!
Fundemort Grey Prime Defender of Truth and Justice And what does this have to do with electricity? It might be partially triggered by electrical signals, but it’s not the (direct) cause of it getting bigger. Also, he said changing with the current.
Actually, there is! Piezoelectric materials do exactly that: they deform when electricity passes through them, something we can exploit to make buzzers. It also works in reverse, so we can generate electricity from deformation (but not much, so it’s typically just used as sensors).
GRBTutorials The impressive thing about these piezo electric crystals you’re talking about is that they are exactly what is used in lighters to create the spark which ignites the flame AND simultaneously are the type of crystals which are used in AFM (Atomic Force Microscopy) to precisely move a observed test-sample with a resolution of just nanometers. AFMs Resolution can be as good as that you can visualise individual atoms!!! It’s ridiculous to imagine that a Cristal like this is capable of being used in field so different from each other! And quartz clocks utilise a small Cristal that if exerted a voltage on vibrates in a very stable and continuous manner.
Now let me tell you this. Back in high school in the 90’s I hated sciences, physics, chemistry and those types of geeky courses, I mean, I truly hated them. It was literally lifeless, colorless and extremely boring blank gibberish recited over and over again by a teacher who didn't give a crap about his work and was more monotonous than a freakin robot. I totally failed and was constantly drawing or worst, sleeping instead. But I can genuinely say that if I had a professor just like you, trust me... Trust me I would have LOVED the courses and even asked for more and more! So glad that I discovered your channel, you really have mind-blowing experiments and outstanding knowledge, and you know how to share it in an exciting digestible way. Amazing work. Time to make up for lost time now, thanks The Action Lab.
*Would the color change if you put them in a vacuum? Or under pressure or extreme temperature?* *Can they expand and contract?* Would that make a difference in the light refraction? 🟥🟧🟨🟩🟦🟪
Having full mastery of specifying wavelengths of light seems like a powerful tool for visual art. You could design a piece of art to appear different ways under different lighting. And current CG software wouldn’t be able to simulate that because for some reason they work with color as if it was just RGB instead of a full spectrum of light. That works for displays, but not really for light bounces.
2:17 I do not like the "size of molecule" things, some polymers have really large molecules. Even the size of atom is relative, because neutron stars are pretty much giant atoms.
@@shivangswain That they are made of neutrons, a subatomic particle, is exactly why NetAndyCz said they can be thought of as a giant atoms. He didn't say that they were made of atoms.
@The Action Lab Nice! You could follow this up with a discussion on color gamuts and color science in general. Something I'm very interested in at the moment. I have a pixel 3a, and it has a wider color gamut than my previous phone. Certainly looks better and is fascinating!
2:05 just goes to show how, even a the minute scale, anything interacting with anything else does so and reacts as per their physical properties, or the way they're shaped
@4:15 He says the variance is only 5nm, but the color on the vials are clearly changing into drastically different colors (and therefore different wavelengths) while the flashlight is on them. I'm guessing it's imperfections in the lighting, but the changes are surprisingly varied.
That's the same thing that happens in blue butterflies They don't actually have blue wings They just have the surface of their wings all carved with valleys however many nanometers in width is needed for you to see the color blue. It's interesting if you get them wet they turn a gray color because the valleys are filled in.
Thanks for this video. I've done a lot of research on oled vs qled, and never really understood QLed. Most websites just say "more pure color" compared to LED or something like that.
Thinking back to before we had TH-cam. We would have to read and sometimes research for a days to learn what we're now able to learn in a few minutes of watching video. I watch around 10 educational videos per day. I'm still not a genius, but better informed.
I’ve experienced first hand the changing of colour of a material according to the size of the particles when I was studying icon painting. We learned how to crush our own pigments to make the tempera paint needed. For that we used different minerals and the most interesting (and expensive) one was lapis lazuli. While crushing it with our glass tool we had to be careful to stop at the right moment because at a certain point the blue pigment started to turn purple and if we didn’t stop we would end up with red instead of blue.
Interesting. But I believe that the color change you speak of was a different phenomenon than here. That was actually due to a chemical reaction with the blue pigment. These quantum dot particles have no pigment in them. The color change is completely a quantum phenomenon due to their size only. Pigments give off multiple wavelengths of light as well (Although you only see one color). These quantum dots only give of one specific wavelength.
The Action Lab I wonder what chemical reaction it could have been. There was only water and the rock and the colour was changing when the rock was crushed into particles of a certain size. We were warned not to crush it too fine cause it turned red. Do you think a reaction with the water couldn’t happen unless the powder was fine enough ?
NetAndyCz exactly. Like the feathers of a blue jay that are only blue at a precise angle but otherwise brown. I though it was the same phenomenon happening with the lapis lazuli.
@@jonathannadeau6218 Well I'm not sure exactly what was going on with your pigment. But I'm sure that it was not due to this quantum phenomenon because to get the color red you would need to have larger particles than the blue ones. Blue is in the 2nm range particle size and red is in the 6nm particle size. So if somehow you were making nanoparticles, grinding more would push them more towards the blue end of the spectrum, not the red. Also, this quantum dot phenomenon only works with semicoductors (like Si, CdTe etc.)
So when you melt down crayons you get a weird brown color, what would happen if you mix all of those? Would you end up with a funky never seen before fluorescent color?
Talking about atoms. Are they really round because I understood that there is no such thing as a bend it's just a series of straight lines under extreme magnification which we cannot achieve. So atoms must be of crystalline structure?
The comments about cadmium being toxic is disturbing. As we become more and more technologically advanced, there are going to be more and more new forms of materials harmful to humans. And yet on the regulatory side, laws tend to be very specific to existing technologies so it's scary that mass production of new and previously exotic materials could be wildly distributed long before regulator oversight has had time to really even give them careful thought. Thumbs up for calling attention to the cadmium issue.
Cadmium dots, yes. There is ongoing effort to use other transition metals, like Si, In, etc. Cadmium is not used in most TVs, to correct the video. For example, the Nanosys film Samsung is using currently in its QLED TVs are ZnSeS, with an Al2O3- shell. They were InP based in 2015 and 2016.
There's a village near where I live that has cadmium contamination dating back to lead mines that were excavated in Roman and pre-Roman times. It's still considered dodgy to grow your own fruit and vegetables there, due to the possibility of cadmium poisoning. Ta.
In the first half of the video I was thinking to myself, “this would work nice in a TV”. Then right after that he starts talking about QLED XD. But just imagine, having the ability to dynamically change the size of these atoms in a TV. So that now TVs work off of a HUE and brightness rather than RGB. So In theory you wouldn’t need 3 sub pixels for one whole pixel. You would just have 1 pixel thats 3 times smaller. Also allowing you to triple the resolution.
No, still RGB. Current QLED TVs use a blue GaN LED backlight for blue on account of the blue dots being finicky, and shine through a film packed with red and green quantum dots, yielding a very pure white backlight for the LCD RGB color filters to then make whatever color they should need. Eventually, they will reach a self-emissive state driven by electrical current vs light stilumus, but will always be RGB. That’s just down to how the human eye perceives color, tbh.
@@TenMillionYearProgram42 Well I know, I was just imagining in the future we might use this principle to develop a different type of color changing light source that doesn't use RGB. Where it would just be a white light source and you can filter all but the wavelength you want. And Since each pixel wouldn't be made of 3 sub pixels it would also, in theory, allow for higher pixel densities.
GHOTI GUY you got a glass tube with a near vacuum and “filled” with mercury vapour. If you ionise Mercury atoms by the means of electricity they radiate uv radiation outwards which on its own would be rather harmful. Glad a layer of phosphorus coated to the inside of the glass tube catches this highly energetic short waved uv radiation which then excites the phosphorus and through a phenomenon called Chemiluminescence the excited phosphorous itself now radiates a set of wavelengths out in retrospect and accordance to the lamps description of light colour. There you go. Might wanna check some of the words for yourself ;)
Hey thanks for this... . . . . . . However which TV do you have....... . . . . . .and another thing i wanna Give you a suggestion, why dont you try putting a large humidifier on top of your fire and air umbrella sticks and vaporise the water by vibrating it.....TRY IT maybe it might work....
Can you make the video of: Anyone (let's say living being) which vibrates and resonates with the same frequency of it barrier (e.g. wall or something) then that human being can penetrate through the wall. This is shown in the season of Flash if you remember. In that The Flash resonates the frequency of its barrier and can penetrate through it.
The way you describe it, makes me think of making a colorless or black/white glasses, or do I think in the wrong direction. Anyway the same way you could make a colorblind see color!?
Can I ask j you a quantum physics question? At a fundamental level is evening waves of energy. So are electrons point like physical objects or a wave of energy. Protons and neutrons are made of quarks, are quarks physical or waves of energy? Theoretically if we could shrink ourselves to subatomic levels or inflate an atom to macro household sizes, that we could see, would we see balls like in the picture we see of quarks, or just detect fluctuations in a field?
I love physics and chemistry, this channel tells me that I really have a good basic understanding from studying it by myself. I just read an article on muons, which have a stronger charge than electrons. So I’m wondering if I could make this video relate to what I learned about muons ? Don’t laugh guys🤔
I’m just a little bit confused how to different particle sizes are retained in solution. For example, if I have coarse ground salt versus fine ground, the size of the grind wouldn’t be retained after dissolution. As I just misunderstanding something here? Is it more along the lines of a polymer where each of the tellurides have a different number of atoms per molecule?
3:34 why doesn't this apply to all materials? When you reduce the material size, you limit the number of diff colors that can be produced by that material.
Darkev it does. You might wanna check out where the “colour” of a butterflies wing comes from. Destin from smarter every day got a great video with electron scanning microscopy of a butterfly. I just say two things: Nature is hecking brilliant and you can make “colour” with holes or pins.
@@timng9104 oh thats cool! But does this "wavelength absorption/emission depending on size" feature apply to specific types of materials, or all of them?
What makes a particle “bigger” than another? What are the “boundaries” of a bigger proton? More space around quarks? And what about electrons? But above all, how do you measure the size of an atom? Sorry I couldn’t stop questioning 😂
Gionata ugh... You ramble a mountain of things in a confused manner most of which you seem to lack basic basic basic understanding. You try to use big word but fail miserably since you didn’t begin at the basics. Start at the bottom and work your way up! Basic chemistry!!! should be a good start considering you think a proton could be “bigger” than another proton. Bohr model of atoms now, atomic orbitals afterwards -> ValenceQuarks and gluons later!
Peter goes to Hollywood that’s why I used the “” at the word bigger. I’m a very big fan of quantum physics but I definitely can’t call myself an expert.. all I meant with all my questions was just trying to understand what he means when he talks about diameters and sizes of atoms, considering he’s referring to the same material :) Always love to learn more, even if the conversations gets a little simplified, when possible of course.

*_The sad thing is, he shows you something, and you learn in a video, which is 6 minutes long, on the other side schools need hours to explain this_*
Amazing!
In the first half of the video I was thinking to myself, “this would work nice in a TV”. Then right after that he starts talking about QLED XD.
But just imagine, having the ability to dynamically change the size of these atoms in a TV. So that now TVs work off of a HUE and brightness rather than RGB. So In theory you wouldn’t need 3 sub pixels for one whole pixel. You would just have 1 pixel thats 3 times smaller. Also allowing you to triple the resolution.
No, still RGB. Current QLED TVs use a blue GaN LED backlight for blue on account of the blue dots being finicky, and shine through a film packed with red and green quantum dots, yielding a very pure white backlight for the LCD RGB color filters to then make whatever color they should need. Eventually, they will reach a self-emissive state driven by electrical current vs light stilumus, but will always be RGB. That’s just down to how the human eye perceives color, tbh.
Andrew900460 the sizes don’t change; they’re static.
@@TenMillionYearProgram42 Well I know, I was just imagining in the future we might use this principle to develop a different type of color changing light source that doesn't use RGB. Where it would just be a white light source and you can filter all but the wavelength you want. And Since each pixel wouldn't be made of 3 sub pixels it would also, in theory, allow for higher pixel densities.
What came to my mind.... how do fluorescence light and mercury vapor lights work?
GHOTI GUY you got a glass tube with a near vacuum and “filled” with mercury vapour. If you ionise Mercury atoms by the means of electricity they radiate uv radiation outwards which on its own would be rather harmful. Glad a layer of phosphorus coated to the inside of the glass tube catches this highly energetic short waved uv radiation which then excites the phosphorus and through a phenomenon called Chemiluminescence the excited phosphorous itself now radiates a set of wavelengths out in retrospect and accordance to the lamps description of light colour.
There you go. Might wanna check some of the words for yourself ;)
How will a 0.1 Nano meter particle of Cadmium telluride will look like under UV
Brighter then the brightest green ?
Hey thanks for this...

.and another thing i wanna
Give you a suggestion, why dont you try putting a large humidifier on top of your fire and air umbrella sticks and vaporise the water by vibrating it.....TRY IT maybe it might work....
I believe the iridescence of butterfly wings is based on its nano physical structure as well.
Brett Cameratraveler it is
On the topic of interesting insect wings, I've read that dragonfly wings have tiny spikes that physically destroy bacteria
Here it is: th-cam.com/video/r1grnyp3Ixk/w-d-xo.html
David Hill wow, I didn’t know this. This is absolutely fantastic. Thanks a lot!
Do these dots keep their color forever? Could they be used as paint replacement? Thank you for your efforts.
Can you make the video of: Anyone (let's say living being) which vibrates and resonates with the same frequency of it barrier (e.g. wall or something) then that human being can penetrate through the wall. This is shown in the season of Flash if you remember.
In that The Flash resonates the frequency of its barrier and can penetrate through it.
What will happen when hydrophobic substance dip into an acid, will it show reaction or it repell water molecules??
I would like to see advancements in the carbon based q-dots definitely less hazardous.
Can you do an experiment for me?
Will the syphon work in vacuum? Does it need atmospheric pressure to take place?
The way you describe it, makes me think of making a colorless or black/white glasses, or do I think in the wrong direction. Anyway the same way you could make a colorblind see color!?
So can’t you mix these liquids to make a bright light vial under UV ?
A small request please define time.
2:35 if sun light does not have any Mass how it can hit out of its level of electron?
And what happen when light hit the Nucleus level?
Can you tell me where you got this?plz.. tell.Help plz.
Would it be possible to make it shine like gold? If you could get any wavelength of light then you should be able to do that right?
Amazing.
Can I ask j you a quantum physics question?
At a fundamental level is evening waves of energy. So are electrons point like physical objects or a wave of energy. Protons and neutrons are made of quarks, are quarks physical or waves of energy?
Theoretically if we could shrink ourselves to subatomic levels or inflate an atom to macro household sizes, that we could see, would we see balls like in the picture we see of quarks, or just detect fluctuations in a field?
Mark Parkinson you wouldn’t “see” at all. And this is a really great question!
Could you make black lightning using your low pressure sodium vapor lamp and a plasma ball filled with sodium vapor?
Does any object have colour then or is it like this and it’s all about the size of of the particles?
Objects have no colour. Light does.
I love physics and chemistry, this channel tells me that I really have a good basic understanding from studying it by myself. I just read an article on muons, which have a stronger charge than electrons. So I’m wondering if I could make this video relate to what I learned about muons ? Don’t laugh guys🤔
Dont u study in any uni?
larpoel Gaming no just at home, and social science in college.
Would this appear blue/violet if the particle size could be made smaller than 2 nanometers? What if you mixed them?
Congratulations, you just invented a new colour ;)
I am krishna from India. My question is why rainbow appears perfect circle?..hope you answer me and understand my question
I knew it, size matters!
So when light strikes it and it bends we see the wave length they showing us ?
So I guess it's not possible buy ready made vials for home decoration right?
Mass effect music in the background.
the tim is nice
Now I've seen ultraviolet brown
I’m just a little bit confused how to different particle sizes are retained in solution. For example, if I have coarse ground salt versus fine ground, the size of the grind wouldn’t be retained after dissolution. As I just misunderstanding something here? Is it more along the lines of a polymer where each of the tellurides have a different number of atoms per molecule?
Today I learned what quantum dots are
Hos does something snapping from one energy level to another create a wave?
3:34 why doesn't this apply to all materials? When you reduce the material size, you limit the number of diff colors that can be produced by that material.
Darkev it does. You might wanna check out where the “colour” of a butterflies wing comes from. Destin from smarter every day got a great video with electron scanning microscopy of a butterfly. I just say two things: Nature is hecking brilliant and you can make “colour” with holes or pins.
Even ligands stabilized gold nanoparticles (spheres, rods ~nm diameters) can be tuned to absorb a range of wavelengths
@@petergoestohollywood382 Awesome thanks for the vid recommendation!
@@timng9104 oh thats cool! But does this "wavelength absorption/emission depending on size" feature apply to specific types of materials, or all of them?
So how do you dispose of them??
*This phenomenon is called "Raman Scattering"*
Not to be confused with "Ramen Scattering", which is what happens when I put too much hot sauce in my ramen.
Over time this guy has grown on me. I guess you could say he won me a banana, you thought I was gonna say 'over' right there but I didn't. Hi.
Imagine new TV technic with this
Like qled TV's he mentioned in the video?
@@vinstinct I wrote the comment before the end of the video and was too lazy to delete it.
What makes a particle “bigger” than another? What are the “boundaries” of a bigger proton? More space around quarks? And what about electrons? But above all, how do you measure the size of an atom?
Sorry I couldn’t stop questioning 😂
Gionata ugh... You ramble a mountain of things in a confused manner most of which you seem to lack basic basic basic understanding. You try to use big word but fail miserably since you didn’t begin at the basics. Start at the bottom and work your way up! Basic chemistry!!! should be a good start considering you think a proton could be “bigger” than another proton. Bohr model of atoms now, atomic orbitals afterwards -> ValenceQuarks and gluons later!
Peter goes to Hollywood that’s why I used the “” at the word bigger. I’m a very big fan of quantum physics but I definitely can’t call myself an expert.. all I meant with all my questions was just trying to understand what he means when he talks about diameters and sizes of atoms, considering he’s referring to the same material :)
Always love to learn more, even if the conversations gets a little simplified, when possible of course.
Gionata im a big fan of economy... doesn’t necessarily mean I know anything about it.
Peter goes to Hollywood oook :)
Gionata Tell me how are 1s^2 2s^2 2p^2 and sodium related?
ls there an artificial Eve?
