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.

In general, what are the advantages of shelling a semiconductor nanocrystal with a metal (say Au@CdSe) in terms of solar cells?

I have not seen any reports based on shelling of semiconductor nanocrystals with metal. In your opinion, do you think shelling a semiconductor nanocrystal(CdSe, CdS, CZTS) with metal(say Au or Ag)...

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?

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.
