Abstract

Abstract

Mixed-halide perovskites have a variety of excellent photovoltaic properties, including the band gap that is widely tunable with the halogen composition, high photoluminescence quantum yield (PLQY), and so on, making them ideal candidates for the photovoltaic device applications such as solar cells and light-emitting diodes. However, mixed-halide perovskites often encounter phase separation under light illumination, which hinders their wide application in optoelectronics. Therefore, investigating the intrinsic mechanism and controlling methods of their phase separation is crucial to improve their properties for practical applications. In this work, a systematic study of the laser-induced phase separation of CsPb(I_xBr_1−x)₃ nanocrystals with different compositions under strong laser irradiation at different pressures was carried out. We discovered that CsPb(I_xBr_1−x)₃ nanocrystals with different I/Br ratios possess different characteristics of laser-induced phase separation, for example, at ambient pressure, the bromine-rich samples with x<0.1 produce nearly full-bromide CsPbBr₃ phase rapidly and achieve a large PLQY gain; the samples with 0.1<x<0.9 clearly form a new photoluminescence (PL) peak at lower wavelength, which represents the bromine-rich phase generation; while the samples with low bromine content with x>0.9 only produce a broadening of the PL peak as well as a rapid decrease of the PL intensity. By subjecting CsPb(I_xBr_1−x)₃ nanocrystals to a quasi-hydrostatic pressure environment, it was observed that phase separation in bromine-rich samples (x<0.9) rapidly slowed down with increasing pressure and was largely suppressed at a mild pressure of about 0.1 GPa, while phase separation in samples with low bromine content was enhanced with increasing pressure. These findings provide an effective and practical way to understand and overcome the problem of application of relevant photoelectric devices in intense light environments.
