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.

存在反向胶束和不同含油量的桑色素线性和非线性性质的研究

我们研究了由恒定水-摩尔比癸烷水微乳液制备的AOT反向胶束中不同浓度（1×10-6和5×10-6 M）的Morin（MN）的线性和非线性光学性质。表面活性剂分子40（W = [H2O] / [AOT] = 40）以及使用UV-Visible获得的纳米液滴（MFD）的质量分数分别为0.01、0.04、0.07和0.1的函数，荧光，FTIR和Z扫描技术。稳态测量表明，微环境的存在可以极大地影响香豆素的互变异构结构，并且微环境中的莫林性质取决于油的量和莫林的浓度。在微环境中，偶极矩从基态到激发态的增加表明了莫林分子结构的变化。
