摘要：

The humidity stability and phase transition mechanism of the all-inorganic perovskite CsPbI2Br based on an optimized dual-source co-evaporation preparation process are investigated at the film interface level. It is found that the CsPbI2Br films annealed at 300(degrees)C for several minutes exhibit a best crystallinity and photoelectric properties. The as-grown CsPbI2Br film is confirmed to be a alpha phase with a dark brown cubic crystal structure and an average visible transparency of 35.9%. But it will be transformed into its delta phase with a transparent orthorhombic crystal structure and...
