摘要
本文报导了以低功率连续波染料激光器为激发光源,所测得的若丹明6G水溶液的反斯托克斯荧光谱。文中还给出了反斯托克斯荧光频移和浓度关系的实验结果。溶液浓度从1×10^(-5)Mol/L到2.4×10^(-3)Mol/L,荧光频移从558nm到580nm。以二聚体模型解释了反斯托克斯荧光频移效应。
The Anti-Stokes fluorescence spectra of rhodamine 6G in water are investigated by a low power CW dye laser. The laser power is 20-30mW. Different laser wavelength has been chosen for different measurements. The concentration of rhodamine 6G dye is varied from 1×105 Mol/L to 2.4×10-3 Mol/L. The fluorescence peak shifts from 558 mn to 580nm approximately, by increasing the concentration. The large peak shift is explained by a dimer model.
