Patent ID: 8664637

Claim:
A quantum dot phosphor, comprising: quantum dots; and a solid substrate on which the quantum dots are supported, wherein the solid substrate comprises a mixture of an inorganic phosphor and a metal oxide, a polymer or a metal salt; wherein the quantum dots are disposed directly on an outer surface defining the solid substrate; and wherein the quantum dot is a Group II-VI compound semiconductor nanocrystal or a mixture of the Group II-VI compound semiconductor nanocrystals, or is a Group III-V compound semiconductor nanocrystal or a mixture of the Group III-V compound semiconductor nanocrystals; and wherein the Group II-VI compound semiconductor nanocrystal is selected from CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, HgS, HgSe, and HgTe, and the Group III-V compound semiconductor nanocrystal is selected from GaN, GaP, GaAs, AlN, AlP, AlAs, InN, InP, and InAs.
