Title:
感光性パターン形成用材料
Document Type and Number:
Japanese Patent JP6447745
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide: a nanoparticle aggregate which is suitable for a photosensitive pattern forming material and the like; a method for producing this nanoparticle aggregate; a nanoparticle aggregate composition; a wavelength conversion layer; and a ligand. The present invention is an aggregate of nanoparticles, each of which comprises: a core-shell nanocrystal having a core containing a semiconductor substance that contains a group 13 element and a group 15 element and one or more shells that cover at least a part of the core and contain a compound that contains a group 12 element and a group 16 element; and a first ligand that covers at least a part of the core-shell nanocrystal. This aggregate of nanoparticles is characterized by exhibiting fluorescence that has a wavelength of from 510 nm to 650 nm (inclusive), a fluorescence quantum yield of 70% or more and a fluorescence half bandwidth of 45 nm or less, if excited by light having a wavelength of 456.2 nm and a half bandwidth of 45 nm in a solvent such as 1, 2-propylene glycol-1-methyl ether-2-acetate.
