I prepared CuInS Quantum dots, unfortunately the XRD pattern is matched the reported results except one plane at 27 2 theta degree. this plane is missing in my data while the other planes are matched
Hi Dear
there is huge discussions on that topic on research gate see the following link

Dear Magdy Ali,
The XRD patterns of powdered samples present all the orientation possible and all the XRD peaks are observed. When you have a prefered orientation on the sample holder like a film of a layered compound, only 00l peaks are observable. When the sample is exfoliated, all the 00l peaks disapear and only the other peaks are observable. Maybe you have a similar situation with your sample.

Fernando
Dear Magdy Ali,
you can access the literature of people working wih layered materiais like micas for example or other phyllosilicates
