摘要：

The fluorescence characteristics of two ketocyanine dyes have been studied in six mixed binary solvents. Several parameters such as the maximum energy E(12)(F) of fluorescence, the quantum yield Phi(12) of fluorescence and the normalized intensity of the fluorescence have been investigated as functions of solvent composition. In protic + aprotic binary mixtures a dramatic change at the aprotic end has been observed. The results point to a preferential solvation of the solute by the protic component.
