Abstract:
1. A quantum dot phosphor, comprising: quantum dots; and a solid substrate on which the quantum dots are supported, wherein the quantum dots are disposed directly on an outer surface defining the solid substrate, each of the quantum dots being separated from the remaining quantum dots; wherein the solid substrate comprises an inorganic phosphor; 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.
