Abstract
The present disclosure relates to a light-emitting composition containing a perovskite compound and inorganic fine particles.
Claims20
A composition having a light-emitting property comprising:
- a perovskite compound including
- a metal ion,
- a monovalent cation positioned at each vertex of a hexahedron having the metal ion at the center in a perovskite type crystal structure,
- at least one anion selected from the group consisting of a halide ion and a thiocyanate ion, the anion being positioned at each vertex of an octahedron having the metal ion at the center in the perovskite type crystal structure;
- and
- inorganic fine particles having a specific surface area of 0.01 m2/g to 150 m2/g, and
- wherein an average particle diameter of the inorganic fine particles is in a range of 3.4 μm to 100 μm.
