Abstract:
Provided are light-emitting particles having high stability while having perovskite-type semiconductor nanocrystals having excellent light-emitting properties, a method for producing the same, and a light-emitting particle dispersion, an ink composition, and a light-emitting element containing such light-emitting particles. The method for producing light-emitting particles of the present invention includes a step of preparing parent particles 91 composed of perovskite-type semiconductor nanocrystals 911 having light-emitting properties and a surface layer 912 which is composed of ligands coordinated on the surface of the semiconductor nanocrystal 911 and in which the ligand molecules form a siloxane bond with each other, and a step of forming a polymer layer 93 by coating the surface of the parent particle 91 with a hydrophobic polymer.
