Thickness-dependent nonlinear optical properties of CsPbBr_3 perovskite nanosheets

Halide perovskite has attracted significant attention because of excellent optical properties. Here, we study the optical properties of CsPbBr_3 perovskite nanosheets and observe that the nonlinear optical properties can be tuned by the thickness. The photoluminescence (PL) properties and nonlinear ...
