| 摘 要： | 利用N_2激光器作为激发光源, 测量若丹明6G(Rh6G)和N,N′-二甲基噻碳菁碘盐(DMTC)不同浓度混合的乙醇溶液的荧光光谱, 证明 Rh6G-DMTC组成施主-受主对, 存在着分子间能量转移效应。通过对DMTC荧光强度与Rh6G浓度的关系的测量, 讨论了Rh6G-DMTC能量转移的机制, 并且导出了辐射转移和Förster转移两种典型过程中受主荧光强度与施主浓度的关系式。

| Abstract: | Using N_2 laser as an excited source, the fluorescence spectra of ethanol solu- tions of rhodamine 6G(Rh6G) and N,N′-dimethyl-carbothiocyanine iodide(DMTC) mixed at various concentrations have been studied. The results show that Rh6G and DMTC compose donor-accepter pair and exist intermolecular energy transfer effect. By means of measuring the relation between DMTC fluorescence intensity and Rh6G concentration, we have discussed the mechanism of Rh6G-DMTC energy transfer and have deduced the relative expressions of accepter fluorescence intensity and donor concentraton for both radiative transfer and Förster transfer processes. |
