摘要	The metal halide perovskite CsPbBr3 films have excellent optical properties, which is an ideal candidate material for full-color display as a wavelength conversion layer in liquid crystal display(LCD). In order to achieve efficient photoconversion from blue to green, CsPbBr3 micron-thick films have been prepared by the pulse laser deposition technique. And the morphology, structure, optical properties are investigated by means of SEM, XRD, and UV-Vis spectrum, respectively. Then the CsPbBr3 micrometer-thick film is deposited on the blue light emitting diode whose emission wavelength is 460 nm, and the performance of light conversion is measured. The results show that the obtained CsPbBr3 films are composed of highly (100)-oriented columnar crystal and the film thickness increases in proportion to the number of laser pulse. When the deposited CsPbBr3 film thickness is 2.252 m, a pure and effective green light emission is achieved under the excitation of blue light(460 nm). In addition, the intensity of photoluminescence(PL) does not decrease significantly when the samples are placed in an air atmosphere(temperature 20, humidity 25%) for 18 days. 2020, Science Press.
