I have prepared a glass sample with rare earth doping. My XRD is as below. Please give suggestions. why this graph got hump, i am confused whether it is correct or wrong. If wrong please suggest me, what corrections has to be done. How to understand the XRD graph. I want go for other characteristics if this result is good, suggest me the other characteristics
Dear Aditya Vamshi ,
I think, you have expected to see an XRD pattern having a few 'crystalline' peaks of well defined small peak withs, well defined peak positions and well defined relative peak heights, which may exhibit slight changes, when your glass sample is doped.
But on the contrary, you only see one or even two broad humps.
Unfortunately the structure of most glass sample is amorphous, that means, that there is no medium or long range periodical order of the atoms or 'molecules' in your sample present.
This amorphous state reflects itself in a hump-structure of the XRD pattern.
You can imagine, that a peak shift, (in your case a slight 'hump shift') or even a slight change of the hump width due to the dopand cannot be seen due to its low concentration.
You may share, what the goal of your investigations is. XRD does not help you here.
For example for investigating the distance of the dopands to the nearest neighbor atoms in the glasss you may use the extended x-ray absorption fine structure (EXAFS) technique in fluorescence mode...( but such experiments are not easiliy done...)
Best regards
