  • Core-alloyed shell semiconductor nanocrystals
    Patent number: 8784685
    Abstract: 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 PbSexS1-x structure; or the core semiconductor material is CdTe and the alloy shell semiconductor material has either the CdTexSe1-x or CdTexS1-x structure.
