Abstract
The present invention relates to a mixture of a compound (1) and a compound (2). The compound (1) is a light-emitting perovskite compound which includes components A, B, and X, and the compound (2) is a light-emitting indium compound or light-emitting cadmium compound. The component A indicates a component positioned at each vertex of a hexahedron having the component B at the center in a perovskite type crystal structure and is a monovalent cation, the component X indicates a component positioned at each vertex of an octahedron having the component B at the center in the perovskite type crystal structure and is one or more kinds of anions selected from the group consisting of a halide ion and a thiocyanate ion, and the component B indicates a component positioned at the centers of the hexahedron where the component A is disposed at each vertex and the octahedron where the component X is disposed at each vertex in the perovskite type crystal structure and is a metal ion.
