METHOD FOR PRODUCING LIGHT-EMITTING PARTICLES, LIGHT-EMITTING PARTICLES, LIGHT-EMITTING PARTICLE DISPERSION, INK COMPOSITION, AND LIGHT-EMITTING ELEMENT

WIPO Patent Application WO/2020/235480

A1

Provided are: light-emitting particles having high stability while having a perovskite-type semiconductor nanocrystal having excellent light-emitting properties; a method for producing the same; a light-emitting particle dispersion including said light-emitting particles; an ink composition; and a light-emitting element. A method for producing light-emitting particles according to the present invention is characterized by having: a step for preparing mother particles 91 each having a hollow particle 912 having an inner space 912a and a pore 912b communicating with the inner space 912a, and a perovskite-type semiconductor nanocrystal 911 received in the inner space 912a and having light-emitting properties; and a step for forming a polymer layer 92 by coating the surface of each mother particle 91 with a hydrophobic polymer.
