Method for producing luminescent particles, luminescent particles, luminescent particle dispersion, ink composition and light emitting device

摘要

Provided are luminescent particles having perovskite-type semiconductor nanocrystals with excellent luminescent properties and high stability, and a method for manufacturing the same, and a luminescent particle dispersion, ink composition, and light emitting device comprising such luminescent particles. The manufacturing method of the luminescent particle of the present invention is composed of a perovskite-type semiconductor nanocrystal 911 having luminescence and a ligand coordinated on the surface of the semiconductor nanocrystal 911, and molecules of the ligand form a siloxane bond. It is characterized in that it has a step of preparing a mother particle (91) having a surface layer (912) and a step of forming a polymer layer (93) by coating the surface of the parent particle (91) with a hydrophobic polymer. do it with
