Abstract
Halide materials with a perovskite crystal structure, particularly CsPbBr3 and Cs4PbBr6, have garnered significant interest for their potential applications in various fields such as LEDs, solar cells, photodetectors. In this study, we reveled the Phase transition of CsPbBr3 to Cs4PbBr6 by reduced temperature gradient. Then, multiple characterization methods are applied to confirm this phase transition. The final results shows that the transformation from CsPbBr3 to Cs4PbBr6 exists at some extent, which indicate its potential application regarding to temperature.
