NIce spin coater ..
So you're using the PC fan as a centrifuge such brilliance.
Materials
Stock Solutions for multiple preparations.
Place approximately 0.30 g PVA (polyvinyl alcohol, Aldrich, 36,316-2, Average MW 124,000-186,000) and 10 mL of water in a 30-mL beaker. Cover the beaker with a watch glass or loosely with plastic wrap. Dissolve the PVA by heating the mixture in a microwave for 5-15 second increments. Do not allow the solution to boil. Stirring with a glass rod may helpDissolve approximately 0.035 g [Ru(bpy)3](BF4)2 (Synthesis) in 3 mL of polyvinylalcohol solution.GaIn Eutectic, Aldrich, 49542-5

I like your spin coater 😉
TH-cam is really a time capsule.
which organic materials are used...?
thank you
Could you share a PDF version of this process please ???
Hi Arafat, we do not have a PDF version of this process, but you can find the written instructions and sources (that have PDF versions) here: education.mrsec.wisc.edu/organic-light-emitting-diodes/
@@WisconsinMrsec thank you so much, I'll share with you all the progresses that I'll make
The way this video cuts off and on and so does the audio makes it mildly disturbing for some reason..
Very nice, Thank you. Any more on OLEDs?
where can I get the materials??
good dyi/diy led video. I see that fan didn't work as planned ,so you used the heat gun., and how the solder was melting in the current. Ideally there's missing dots, but visiting this video again . Have a good one
that was gallium or indium not solder. after reading the page in the description i figured that out.
Good idea for the spin coater
it doesn't have any backlight support?
If it had sound how it was done it would have been a good thing to try to improve it and inventing new products
nice electrodes ..
what are the samples and chemicals you are using?
good video !!! this is a good experiment for school , where can i buy the material ? , thanks
It’s easy to find most of the materials but the ruthenium salt is really expensive. Half a gram will cost about $200
@@Funnyfish458 damn
Very cool!
can tell me the materials? and where i could find it
What is the device area here?
amazing!!!
How do you make blue and green
Could someone tell me why my four OLED devices with the same concentration of solutions, same conditions and same sizes could have very different currency efficiency, , performance etc?? I do the spin coating and patterning within 20 minutes for 4 pieces.
Can that because of the contamination of solutions or solvents or equipments, or due to my bad spin coating skills, or unbalance of the spin coating machine etc? What could be the factors?
Maybe different resistance in all LEDs. .
why not uranium aluminum iodinephosphorus screen?
Now I want to make my own LEDs
Does it have rectifying properties as well?
Hi Abdolazim, these do function as diodes, such that you should only see current flow and light when voltage is applied in the correct orientation. Hope that helps!
Love It...
Very nice
Great
Thanks for that, I totally got what you were doing thanks to the indepth dialogue explaining the process..................................SHITE
I understand your frustration that there is no dialogue during the video, but you can find the full procedure at the website linked in the description.
Cool!
How on earth is tin oxide or metal organic?
The Kaiser when they talk about organic light emitting Diodes, they mean the emitting layers. In this case the red light is emitted by an organic compound. The electrodes indeed are non-organic in this case.
Michael Dorner What is organic about the compound?
By "organic" is meant that the substance has carbo-hydrates in it. Those are mostly complex chemical structures which are synthetic (not "natural organics" as you might think) - but a lot of them indeed are environmentally friendly or even biodegradable. It's a Hype because it was not possible to organic chemicals to do all the cool stuff that metal did the past decades like be conductive or emit light and stuff..
Michael Dorner Mmmh, tasty, I like carbohydrates.
What exactly is the organic substance here?
The Kaiser not carbohydrates. He means "carbon-based". The organic in this case seems to be poly vinyl alcohol.
I'm here after watching Dr. stone.
is the ITO layer patterned or it's not necessary?
Explanations would have enhanced the video
Hi Electro, moving forward we plan to include explanations in addition to the written instructions, which can be found here for this video: education.mrsec.wisc.edu/organic-light-emitting-diodes/
👀👏🏼
#nilered
OMG! Is that a Hg ?!! Toxic OLEDs :)
indium gallium eutectic...
Anyone asking for the materials contact me
Help me I need them
help, please
😬
Diodo a baffo di gatto. "th-cam.com/video/nymu1z8_C7s/w-d-xo.html", carbonio (C) e germanio (Ge) due elementi organici
Ok, so you made something with something. If there’s no explanation, why put up the video, you wanna pat in the back or something.
Prepare to Die-ode
Unless You Explain in detailed video has no meaning.
Hi Gaurang, these videos were meant to accompany written text, which can be found here: education.mrsec.wisc.edu/organic-light-emitting-diodes/
