若丹明6G-甲酚紫分子间能量转移的荧光光谱研究
摘要:
本文研究了若丹明6G-甲酚紫组成施主-受主对的混合乙醇溶液中分子间能量转移的机制. 着重研究了甲酚紫的荧光强度与其浓度的变化关系. 在甲酚紫的浓度较高时, 其自吸收效应对荧光强度影响很大, 不能忽略. 考虑了甲酚紫的自吸收效应之后, 对Boirks的理论公式做了修正, 得到了辐射转移和Forster转移两种过程中受主荧光强度与受主浓度的关系式。

Fluorescence Spectroscopic Studies on Intermolecular Energy Transfer of RH6G-Cresyl Violet Mixture Solution
Abstract:
In this paper, we have studied the mechanism of intermolecular energy transfer of Rh6G and Cresyl Violet which form a donor-acceptor pair in mixture solution. The relationship between the fluorescence intensity of Cresyl Violet and its concentration has been emphatically studied. The effect of self-absorption of Cresyl Violet upon the fluorescence intensity is appreciable and can not be ignored, as the concentration of Cresyl Violet being high. Considering the effect of self-absorption, we have mo-dified the theoretical formula obtained by Birks, and deduced the relative expressions of acceptor fluorescence intensity and acceptor concentration for both radiative transfer and Forster transfer processes.
