Abstract:

Inorganic lead halide perovskite CsPbX₃ (X=Cl,Br,I) has excellent photoelectric properties such as high optical absorption coefficient, narrow emission line width and high luminescence. Compared with the organic-inorganic hybrid halide perovskite commonly used in photovoltaic fields, the chemical and heat stability of CsPbX₃ is much better. In this paper, several preparation methods of CsPbX₃ crystal were analyzed and recent progresses in the fields of photodetector, LED, laser and high energy detector were summarized.
