Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a composition more excellent in light absorption characteristics and a method for using the same.SOLUTION: A composition has crystalline particles containing cation and anion, where 10 mol or more and 95 mol% or less of the cation is a group 14 element cation, 5 mol% or more and 90 mol% or less of the cation is a countercation, here, the countercation contains two or more cations, 5 mol% or more and 95 mol% or less of the anion is a group 17 element anion, 5 mol% or more and 95 mol% or less of the anion is a molecular anion, the crystalline particles have such an octahedral structure that the group 14 element cation is six-coordinated to the group 17 element anion and such a structure that the octahedrons share apexes and at least total 4 octahedrons are connected to each other.SELECTED DRAWING: None
