Title:
MIXTURE CONTAINING PEROVSKITE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/168638
Kind Code:
A1
Abstract:
The present invention relates to a mixture comprising compound (1) and compound (2). Compound (1) is a luminescent perovskite compound comprising components A, B, and X. Compound (2) is a luminescent indium compound or a luminescent cadmium compound. Component A is a component which lies at the apexes of a hexahedron, in the perovskite crystal structure, that includes component B as the center and which is monovalent cations; component X is a component which lies at the apexes of an octahedron, in the perovskite crystal structure, that includes component B as the center and which is ions of one or more kinds selected from the group consisting of halide ions and thiocyanate ions; and component B is a component which lies at the centers of both the hexahedron, including component A disposed at the apexes, and the octahedron, including component X disposed at the apexes, in the perovskite crystal structure, and which is a metal ion.
