Title:
LIGHT-EMITTING SEMICONDUCTOR COMPOUND AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/024804
Kind Code:
A1
Abstract:
A compound having a perovskite crystal structure having A, B, and X as constituent components thereof (in the perovskite crystal structure, A is a monovalent positive ion and a component positioned at each vertex of a hexahedron centered on B; B is a metal ion and a component that is at the center of a hexahedron having A positioned at the vertices thereof and an octahedron having X positioned at the vertices thereof; X is a component positioned at each vertex of an octahedron and is at least one type of negative ion selected from the group consisting of a halogen compound ion and a thiocyanate ion). The compound has a primary particle size of 100 nm – 1.0 μm and shows a peak for a Miller index (110) plane having a half width of 0.10–0.30°, in an X-ray diffraction pattern.
