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.

Is it possible to determine the concentration of CZTS nanoparticles using the absorption spectra (UV-VIS)?

Usually, CZTS nanoparticles have a broad range of absorption extending to the edge of NIR region and I need to calculate the concentration of CZTS nanoparticles in the solution.

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?
