Title:
COMPOSITION, FILM, LAMINATED STRUCTURE, LIGHT-EMITTING DEVICE, AND DISPLAY
Document Type and Number:
WIPO Patent Application WO/2018/117132
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting composition comprising (1), (2), and (3). Said (1) consists of semiconductor particles, (2) is an organic compound including a mercapto group, and (3) is at least one type selected from the group consisting of polymerizable compounds and polymers. Said (1) preferably consists of particles of a perovskite compound comprising A, B, and X as constituent components. Said A is a component located at each apex of a hexahedron centered about B in the perovskite-type crystal structure, and is a monovalent positive ion. X represents a component located at each apex of an octahedron centered about B in the perovskite-type crystal structure, and is at least one type of negative ion selected from the group consisting of halide ions and a thiocyanate ion. B is a metallic ion.
