The invention relates to a core-alloyed shell semiconductor nanocrystal comprising: (i) a core of a semiconductor material having a selected band gap energy; (ii) a core-overcoating shell consisting of one or more layers comprised of an alloy of the said semiconductor of (i) and a second semiconductor; (iii) and an outer organic ligand layer, provided that the core semiconductor material is not HgTe. In certain embodiments, the core semiconductor material is PbSe and the alloy shell semiconductor material has the PbSeSstructure; or the core semiconductor material is CdTe and the alloy shell semiconductor material has either the CdTeSeor CdTeSstructure.

Core-alloyed shell semiconductor nanocrystals

A method is provided for producing semiconductor nanoparticles comprising: (i) dissolving a semiconductor compound or mixture of semiconductor compounds in a solution; (ii) generating spray droplets of the resulting solution of semiconductor compound(s); (iii) vaporizing the solvent of said spray droplets, consequently producing a stream of unsupported semiconductor nanoparticles; and (iv) collecting said unsupported semiconductor nanoparticles on a support.
