Title:
SEMICONDUCTOR-NANOPARTICLE-CONTAINING COMPOSITION, WAVELENGTH CONVERSION FILM, LIGHT-EMITTING DISPLAY ELEMENT, AND METHOD FOR FORMING WAVELENGTH CONVERSION FILM
Document Type and Number:
WIPO Patent Application WO/2019/167751
Kind Code:
A1
Abstract:
Provided are: a semiconductor-nanoparticle-containing composition which has high dispersion stability and gives a wavelength conversion film having a high fluorescence quantum yield; a wavelength conversion film and a light-emitting display element each formed from such semiconductor-nanoparticle-containing composition; and a method for forming the wavelength conversion film. The semiconductor-nanoparticle-containing composition of the present invention comprises (A) semiconductor nanoparticles, (B) light-diffusing particles, and (C) a compound having a carboxy group, a sulfo group, a phosphate group, or a combination of these and having an acid value of 5-200 mg-KOH/g, wherein the semiconductor nanoparticles (A) have a first ligand, which includes both a carboxy group, thiol group, phosphono group, amide group, or combination of these and an ether group, ester group, siloxane group, or combination of these.
