若丹明6G分子反斯托克斯荧光温度效应

Temperature Effect of Anti-Stokes Fluorescence of Rhodamine 6G Molecules

用２０毫瓦氦氖激光器作为激发光源，研究了若丹明６Ｇ水溶液反斯托克斯荧光谱。反斯托克斯荧光强度随溶液温度有强烈依赖关系。当温度由２３℃升高到４３℃时，反斯托克斯荧光强度增加三倍。根据热平衡分布规律讨论了反斯托克斯荧光强度与温度的依赖关系。

:AntiStokes fluorescence spectra of rhodamine 6G in solution are investigated by a 20mw HeNe laser.The temperature dependence of fluorescence was measured.The fluorescence intensity is sensitively changed with temperature of the solution.The fluorescence intensity is three times increase by changing the temperature from 23℃ to 43℃.The temperature dependence of antiStokes fluorescence has been discussed by thermal equilibrium distribution.
