Patent ID: 8288153

Claim:
A luminescent semiconductor nanocrystal composition, comprising: a semiconductor core comprising a first semiconductor material selected from the group consisting of a II-VI semiconductor and a III-V semiconductor; a core-overcoating shell comprising a second semiconductor material which is different from the first semiconductor material the second semiconductor material being selected from the group consisting of MgS, MgSe, MgTe, CaS, CaSe, CaTe, SrS, SrSe, SrTe, BaS, BaSe, BaTe, ZnS, ZnSe, ZnTe, CdS, CdSe, CdTe, HgS, HgSe, and HgTe, and wherein the core and the core-overcoating shell form a core/shell nanocrystal; and a polymer.
