文摘The Iluorescence quantum yields and lifetfors T of 1,5-diphenyl-3 naphthyl-2-pyrazoline were measured in methanol/glycerol and cyclohexane/llquid paraf fin Anxed systems at 288K. Results indicated that the ratio T/ .f was found to be viscosity independent and equal to the intrinsic radiative lifetime Th calculated from the integrated absorption spectra.
