Title:
QUANTUM DOT AND METHOD FOR MANUFACTURING SAME, AND WAVELENGTH CONVERSION MEMBER, ILLUMINATION MEMBER, BACKLIGHT DEVICE AND DISPLAY DEVICE USING QUANTUM DOT
Document Type and Number:
WIPO Patent Application WO/2020/196064
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an InP quantum dot having good fluorescence characteristics by improving a phosphor starting material thereof. The quantum dot according to the present invention, which contains at least In and P, is characterized in that P is derived from triphenyl phosphite. Preferably, the quantum dot has a core-shell structure in which a nanocrystal serving as a core is surface-coated with a shell. Preferably, the fluorescence wavelength thereof is 450 nm or more. Preferably, a ligand is provided on the surface of the quantum dot.
