We investigate the linear and nonlinear optical property of Morin (MN) at different concentration (1 × 10-6 and 5 × 10-6 M) within AOT reversed micelle prepared by water-in-decane microemulsion having a constant molar ratio of water-to-surfactant molecules of 40 (W = [H2O]/[AOT] = 40) as well as the function of mass fraction of nano-droplet (MFD) values of 0.01,0.04, 0.07, and 0.1 by using UV-Visible, Fluorescence, FTIR, and Z-scan techniques. The steady-state measurement indicates that the presence of microenvironment can greatly affect the tautomeric structure of morin and also Morin property in microenvironment depends upon the amount of oil and Morin concentration. The increase in dipole moment from the ground state to excited state in microenvironment indicate the change in the molecular structure on morin. Morin does not show any nonlinear absorption property but the nonlinear refractive index is observed as a function of Morin concentration as well as MFD values which are due to the thermal agitation of formed dimers. Morin nonlinearity.
我们使用紫外可见光谱、荧光光谱、傅里叶变换红外光谱和Z扫描技术,研究了在水与表面活性剂分子摩尔比恒定为40(W = [H₂O]/[AOT] = 40)的癸烷包水微乳液制备的AOT反胶束中,不同浓度(1×10⁻⁶和5×10⁻⁶ M)的桑色素(MN)的线性和非线性光学性质,以及纳米液滴质量分数(MFD)值分别为0.01、0.04、0.07和0.1时的情况。稳态测量表明,微环境的存在会极大地影响桑色素的互变异构结构,并且微环境中桑色素的性质取决于油的含量和桑色素浓度。微环境中从基态到激发态偶极矩的增加表明桑色素分子结构发生了变化。桑色素未表现出任何非线性吸收特性,但观察到非线性折射率是桑色素浓度以及MFD值的函数,这是由于形成的二聚体的热搅动所致。桑色素的非线性特性。
