Document Type and Number:
WIPO Patent Application WO/2019/069737
Kind Code:
A1
Abstract:
Provided are: particles wherein a dispersing agent can be easily removed from semiconductor nanocrystals; an ink having excellent storage stability; and a light-emitting element having a long light-emitting life. Particles according to the present invention are constituted by: light-emitting semiconductor nanocrystals; and a dispersing agent supported by the semiconductor nanocrystals and having a boiling point of lower than or equal to 300°C at atmospheric pressure. An ink according to the present invention comprises: said particles according to the present invention; and a dispersion medium having a boiling point, at atmospheric pressure, that is higher than or equal to the boiling point of the dispersing agent at atmospheric pressure, and including a polar compound having a polar group.
