As laser technology advances, the importance of laser protection puts an urgent demand for robust and high-efficient optical limiting materials. In this work, CsPbX3 (X = Cl/Br, Br) NCs were synthesized by precisely controlling the ratio of Cl(- )to Br- and the heat treatment temperature, and the third-order nonlinear (TONL) optical properties of them were investigated systematically and deeply based on a nonlinear optical imaging technique with the phase-object (NIT-PO) at 532 nm for the first time. All of them demonstrate strong reverse saturation absorption (similar to 10(-12)-10(-11) m/W), and the sign of TONL refraction index (gamma) relates to the component (CsPb(Cl/Br)(3) NCs glasses: similar to 10(-20) m(2)/W, CsPbBr3 NCs glasses: similar to -10(-20) to 10(-19 )m(2)/W). In addition, they have excellent characteristics of thermal stability and water stability, as well as photostability under 455 nm laser irradiation, indicating that it is a promising optical limiting material.
