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.
