Abstract

Perovskite materials receive much attention due to their promising applications and have been a hot research topic in the field of optoelectronics. The advantages of two-dimensional CsPbBr₃ perovskite nanosheets are easy film formation, anisotropy, and better in-plane carrier transport channels. Different methods are used in experiments to modulate their morphological dimensions and modulate in terms of luminescence, photoelectric effect and carrier transport behavior to obtain enhanced optoelectronic properties. Two-dimensional CsPbBr₃ perovskite nanosheets were synthesized by using the thermal injection method, maintaining the experimental conditions of no water and no oxygen, and continuously passing nitrogen gas at a high temperature of 180°C. The analysis revealed narrow absorption and emission peaks, small Stokes shifts and half-height widths, and a fluorescence lifetime of 60.5 ns. It is shown that the two-dimensional CsPbBr₃ perovskite nanosheets fabricated by this method have easily tunable fluorescence spectral properties and have important application prospects in the field of future optoelectronic devices.
