Thank you for the comment. In some of the research articles, you can see the particle size is mentioned as the mean value. Consider one of your images has 50 particles with size 100-200 nm^2 and 5 particles with 1000-2000 nm^2. If you put the mean size in your journal article, the reader may not get any clear idea about how the particles are arranged (range of sizes even if you put the error component). However, with the distribution curves, you can get an idea about the skewness of the distribution, especially when your samples have a wide range of particle sizes.
is it necessary that your particle size you found in XRD and SEM should be same or not? My particle size found in XRD is 10nm before doing and after doping it was 6nm .... Please help me to solve this confusion....
Hello. What you are measuring from XRD is the Crystallite size. Particle size may differ from crystallite size. Some practicals may consist of several crystallites. To get a better understanding, please google the comparison of particle size vs grain size vs crystallite size. Good luck!
Thank you for your comment. I think it's better to use BET analysis if you are using porous materials. Even though SEM can provide Z-Axis data using the greyscale, you can not accurately calibrate it. Without the Z-axis, you can't discuss volumes. You can measure pore diameters (and areas) using this method. If you want to get Z-axis details and obtain volume information, use Gwyddion, and you may get some values. I'm not sure about its accuracy.
Dear Master, could you please make a video regarding the XRD peak analysis, EDS spectra analysis? If it understanding means I'll feel comfortable in characterisation. Kindly accept my request. Thank you in an advance.
You can simply import images that are in PDF format to Photoshop. Then you can save it in an acceptable format. Or you can use online PDF to JPG converters.
You can do it by Image>Color>Channel tool and in the window, select "more" button. From there you can change. But I highly recommend you not to do that. Keep the standard gray scale in SEM images.
What are the units of particle size in the sem image? is it area or just length of the particle?
Since we input the units in nanometers, all the measurements will be in nanometers. This video demonstrates area measurements.
Thank you for this excellent demonstration, I have one question, what is the importance of the distribution after I get the results?

Beautiful presentation with beautiful content... Thank you, Master.... Thanks a lot...

Thank you for the video. It is very educative. Please how can I use it for pore size and volume?. Thank you

Thank you sir, very good and correct explanation sir
thank you so much , please unit of particle size ?
Since we input "nm" as the unit, it will give all the dimensions in "nm".
@@amc-tec7721 ok thnak you 😇
it is so good what type of soiftware is used
It's ImageJ. An opensource sofrware.
Dear Master,
could you please make a video regarding the XRD peak analysis, EDS spectra analysis? If it understanding means I'll feel comfortable in characterisation. Kindly accept my request.
Thank you in an advance.
Sure. I'll make some videos regarding those characterization and related softwares. Thank you for the suggestion.
great job....
Beautiful Explanation Thanlkyou SO much
Really appreciate your feedback.
Good work
Thank you...
Thank u sir
how to take images which are in pdf format.
You can simply import images that are in PDF format to Photoshop. Then you can save it in an acceptable format. Or you can use online PDF to JPG converters.
how to color sem images
You can do it by Image>Color>Channel tool and in the window, select "more" button. From there you can change. But I highly recommend you not to do that. Keep the standard gray scale in SEM images.
@@amc-tec7721 great... thank u Sir
