What could be a better ligand in terms of colloidal stability for CZTS nanoparticles?

I use Oleylamine and Octadecene as the ligand to cap my CZTS@Ag core shell nanoparticles. However, I have found that after 2-3 wash (washing with ethanol and dispersing in toluene) the particle...

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...

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?
