Abstract

The nonlinear optical properties, absorbance and fluorescence spectra of Erythrosin B (ErB) aqueous solution in different CTAB concentration was studied. Z-scan technique under laser light excitation at 532 nm, was used for study reverse saturable absorption (RSA) of ErB. it was observed that the RSA of solution depend on CTAB concentration. A enhancing of absorbance and quenching of fluorescence is observed with increase of CTAB concentration in solution and the RSA can reduce the fluorescence intensity. It was proposed that the micelle can reduce the dye aggregation is solutions and it can affect on linear and nonlinear optical properties of ErB.

阴离子表面活性剂对红素B光学性质的传感

研究了红素B (ErB)水溶液在不同CTAB浓度下的非线性光学性质、吸光度和荧光光谱。采用532 nm激光激发下的z扫描技术，研究了ErB的反饱和吸收(RSA)。观察到溶液的RSA与CTAB浓度有关。随着溶液中CTAB浓度的增加，荧光的吸光度增强和猝灭，RSA可以降低荧光强度。提出胶束可以减少染料在溶液中的聚集，并影响ErB的线性和非线性光学性质。
