  • Publication number: 20220195290
    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 each having hollow particles 912 each having an inner space 912a and pores 912b communicating with the inner space 912a, and perovskite-type semiconductor nanocrystals 911 contained in the inner space 912a and having light-emitting properties, and a step of coating the surface of each parent particle 91 with a hydrophobic polymer to form a polymer layer 92.
    Type: Application
