Title:
LUMINESCENT-PARTICLE-CONTAINING INK COMPOSITION, LIGHT CONVERSION LAYER, AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/054590
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a luminescent-particle-containing ink composition that exhibits excellent thermal stability during heating, and also provide a light conversion layer and a light-emitting device that use said ink composition. The luminescent-particle-containing ink composition according to the present invention is characterized by containing: nanoparticles that include semiconductor nanocrystals having a perovskite-type structure; a photopolymerizable compound; a photopolymerization initiator; and a hypophosphite diester compound. The hypophosphite diester compound preferably has a molecular weight between 500 to 1,500 inclusive, and a softening point and a melting point between 70°C to 250°C inclusive.
