Abstract
The present disclosure relates to a perovskite that includes A1-xA′xBX3, where A is a first cation, A′ is a second cation, B is a third cation, X is a first anion, and 0<x≤1. In some embodiments of the present disclosure, the perovskite may further include a second anion (X′) such that the perovskite includes A1-xA′xB(X1-zX′z)3, where 0<z≤1. In some embodiments of the present disclosure, the perovskite may further include a fourth cation (A*) such that the perovskite includes A1-x-yA′xA*yB(X1-zX′z)3, where 0<y≤1. In some embodiments of the present disclosure, the perovskite may further include a fifth cation (B′) such that the perovskite includes A1-x-yA′xA*yB1-aB′a(X1-zX′z)3, where 0<a≤1.

A perovskite comprising:
- A1-xA′xBX3, wherein:
- A is a first cation, A′ is a second cation, B is a third cation, X is a first anion, and 0<x≤1.
A method comprising:
- combining a first perovskite and a second perovskite, wherein:
- the first perovskite has a first composition comprising a first cation (A), a second cation (B), and a first anion (X),
- the second perovskite has a second composition comprising a third cation (A′), a fourth cation (B′), and a second anion (X′), and
- the combining results in the forming of a third perovskite having a third composition comprising at least three of A, A′, B, B′, X, or X′.
