Title:
QUANTUM DOT AND METHOD FOR PRODUCING SAME, RESIN COMPOSITION, WAVELENGTH CONVERTING MATERIAL, AND LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/111617
Kind Code:
A1
Abstract:
The present invention is a quantum dot containing a semiconductor crystal particle having a particle diameter of 20 nm or less, the quantum dot being characterized in that a ligand having at least two functional groups each capable of interacting with the semiconductor crystal particle is coordinated on the surface of the semiconductor crystal particle at least bidentately. A quantum dot can be provided, in which the surface of a semiconductor crystal particle is modified with a ligand that has at least two functional groups each capable of interacting with the semiconductor crystal particle and can coordinate on the surface of the semiconductor particle at least bidentately, and which has improved stability.
