The fluorescence quantum yields Фf and lifetimes τ of 1,5-diphenyl-3 naphthyl-2-pyrazoline were measured in methanol/glycerol and cyclohexane/liquid paraffin mixed systems at 288K. Results indicated that the ratio τ/Фf was found to be viscosity independent and equal to the intrinsic radiative lifetime τo calculated from the integrated absorption spectra. In addition, the process of nonradiative decay of the title compound TPP was discussed.
