QUANTUM DOT-METAL OXIDE COMPOSITE, METHOD FOR PRODUCING QUANTUM DOT-METAL OXIDE COMPOSITE, AND LIGHT-EMITTING DEVICE CONTAINING QUANTUM DOT-METAL OXIDE COMPOSITE

摘要

PROBLEM TO BE SOLVED: To provide a quantum dot-metal oxide composite, a method for producing the quantum dot-metal oxide composite, and a light-emitting device containing the quantum dot-metal oxide composite.;SOLUTION: The quantum dot-metal oxide composite includes quantum dots and a metal oxide forming a three-dimensional network with the quantum dots. The quantum dots are an Si-based nano-crystal, a II-VI-based compound semiconductor nano-crystal such as CdSe, a III-V-based compound semiconductor nano-crystal such as GaN, or a IV-VI-based compound semiconductor nano-crystal such as SbTe. The metal oxide is an oxide of Si, Ti, or Al. The quantum dot-metal oxide composite is obtained by treating the surface of the quantum dots with an amino-alcohol and the like, then reacting the metal oxide therewith, and forming a three-dimensional network, and is used as a wavelength converting portion of the light-emitting device.;COPYRIGHT: (C)2010,JPO&INPIT
