I have a SAED pattern of the hybrid nanostructure (metal and semiconductor) but I am not sure what information should I get from this image?

This SAED pattern is generated for a metal semiconductor hybrid nanostructure. I can see it's not single crystalline but I am not sure how to index the planes? Could you please help?

Do you get a peak shift of core in case of tiny core shell nanoparticles?

How reliable the powder XRD data is in case of small hybrid (metal @semiconductor) core shell nanoparticles say 12nm in size? Do you observe a small shift? The sample is not highly crystalline.

What are the possibilities for the formation of Ag2S (Silver sulfide) nanocrystals/nanoparticles instead of deposition of Ag+ ions on a CZTS NCs?

I have seen few reports for the binding of silver ions to sulfur and forming silver sulfide when depositing silver on a semiconductor nanocrystals such as CdS, PbS, CZTS. Why? What are the...

Why is it difficult to grow a perfect core shell nanostructures with semiconductor nanocrystals as cores and metal as shell?

I always get nucleation of metals onto the facets or on the defect sites or they just form separate islands. Any suggestions to achieve homogeneous nucleation?
