Controlling the Defects of Cs2AgBiBr6 by Varied Precursor Compositions

Advanced Photonics Research, 2022
The amount and type of defects in Cs2AgBiBr6 are controlled by varying the Ag/Bi ratio of the precursor solutions in two different synthesis routes, that is, slow solution cooling crystallization and fast microwave‐assisted hydrothermal synthesis.
