Nonlinear Optical Properties of Colloidal CH3NH3PbBr3 and CsPbBr3 Quantum Dots: A Comparison Study Using Z-Scan Technique

The comparison between organic–inorganic CH3NH3PbBr3 quantum dots and all inorganic halide perovskite CsPbBr3 quantum dots allows to understand the structural difference and corresponding optical properties. Using Z‐scan measurements, it is revealed that colloidal CH3NH3PbBr3 exhibits enhanced two‐p...

Zusammenfassung:	The comparison between organic–inorganic CH3NH3PbBr3 quantum dots and all inorganic halide perovskite CsPbBr3 quantum dots allows to understand the structural difference and corresponding optical properties. Using Z‐scan measurements, it is revealed that colloidal CH3NH3PbBr3 exhibits enhanced two‐photon absorption properties compared to those of CsPbBr3 quantum dots due to their structural difference.
