摘要：

Metal halide perovskites have been considered as nonlinear optical materials owing to their favorable optics properties. Though CsPbBr3 nanocrystals (NCs) are popularly emerging in optoelectronic devices, there has been little research on its nonlinear optical properties. In this work, emission-tunable CsPbBr3 NCs were prepared by solution method at room temperature, and employed as saturable absorber (SA) to investigate its nonlinear optical properties. The cubic CsPbBr3 NCs with 482 nm emission as SA showed the modulation depth of 3.7% and saturable strength of 0.91 MW cm-2. CsPbBr3 NCs have a maximum repetition rate of 840 kHz and a pulse width corresponding to 76 ns. The nonlinear optical properties of CsPbBr3 NCs indicate their great potential applications in nonlinear optics and optical communication.
