Nanoparticle aggregate and its manufacturing method, nanoparticle aggregate composition, wavelength conversion layer and ligand

摘要

The purpose of the present invention is to provide a kind of nanoparticle aggregate for being suitable for photonasty material for pattern-forming etc., the manufacturing method of the nanoparticle aggregate, nanoparticle aggregate composition, wavelength conversion layer and ligands. The present invention is a kind of aggregate with core-shell nano crystallization and the nanoparticle of the 1st ligand, core-shell nano crystallization includes the core comprising the semiconductor substance containing the 13rd race's element and the 15th race's element and is coated at least part of the core and comprising one or more shells containing the 12nd race's element and the compound of the 16th race's element, 1st ligand is coated at least part of the core-shell nano crystallization, and the nanoparticle aggregate is characterized in that, 1, in the solvents such as 2- propylene glycol -1- methyl ether -2- acetic acid esters, when utilization half value width is the 456. of 45nmWhen the light excitation of the wavelength of 2nm, generation fluorescence quantum yield is 70% or more and fluorescence half value width is the fluorescence of 45nm 510nm or more below and 650nm wavelength below.
