Title:
化合物、分散液組成物、樹脂組成物、膜、積層構造体及び発光装置
Document Type and Number:
Japanese Patent JP6948168
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a compound having a perovskite structure with high emission intensity, and a dispersion composition and a resin composition including the compound.SOLUTION: The compound has a perovskite crystal structure comprising A, B, X, M1 and M2 as components, in which a molar ratio [(M1+M2)/(M1+M2+B)] obtained by dividing the total molar numbers of M1 and M2 by the total molar numbers of M1, M2 and B, is 0.7 or less. In the above components, A represents a cesium ion, an organic ammonium ion or an amidinium ion; B represents a lead ion; M1 represents a cation of monovalent metal element having an ionic radius of 0.5Å or more and 1.6Å or less; M2 represents a cation of trivalent metal element having an ionic radius of 0.3Å or more and 1.6Å or less; and X represents a component located at each apex of an octahedron with B as the center and represents at least one anion selected from the group consisting of a chloride ion, a bromide ion, a fluoride ion, an iodide ion and a thiocyanate ion.SELECTED DRAWING: None
