Abstract

An F-scan nonlinear spectrometer is used to measure the two-photon absorption coefficient for CHNHPbBr perovskite films from 690 to 995 nm. This spectrometer uses an electrically focused tunable lens and a tunable femtosecond-pulse laser (Mai Tai-HP) with a resolution of 5 nm. Two-band models and saturation irradiance corrections are used to fit the experimental data. The nonlinear absorption in this wavelength range is of the order of cm/MW. We found that the best agreement between the experimental data, the reported values in the literature, and the theoretical model is obtained for an extended two-band model with irradiance saturation correction.

摘要

使用F扫描非线性光谱仪测量CHNHPbBr钙钛矿薄膜在690至995nm范围内的双光子吸收系数。该光谱仪使用电聚焦可调谐透镜和分辨率为5nm的可调谐飞秒脉冲激光器（Mai Tai-HP）。采用双波段模型和饱和辐照度校正来拟合实验数据。该波长范围内的非线性吸收量级为厘米/兆瓦。我们发现，对于具有辐照度饱和校正的扩展双波段模型，实验数据、文献报道值和理论模型之间的一致性最佳。
