One-Step Fabrication of 0D Cs₄PbBr₆ Perovskite with Nonlinear Optical Properties for Ultrafast Pulse Generation.

ABSTRACT: Low-dimensional lead halide perovskites demonstrate remarkable nonlinear optical characteristics attributed to their distinctive physical structures and electronic properties. Nevertheless, the investigation into their nonlinear optical properties remains in its incipient stages. This study addresses this gap by precisely controlling solvent volumes to synthesize both 0D Cs₄PbBr₆ and Cs₄PbBr₆/CsPbBr₃ perovskites. Remarkably, as saturable absorbers, both pure Cs₄PbBr₆ and Cs₄PbBr₆/CsPbBr₃ composites exhibit favorable nonlinear optical properties within the C-band, showcasing modulation depths of 9.22% and 16.83%, respectively. Moreover, for the first time, Cs₄PbBr_6</
