Abstract

From the room-temperature fluorescence lifetimes of benzo(f)quinoline and 4-phenylphenol adsorbed on filter paper and earlier luminescence data, several photophysical parameters were calculated. Also, a number of equations that relate radiative and nonradiative rate constants to pre-exponential factors and activation energy terms were considered. By combining the luminescence data obtained in this work and previous luminescence data acquired as a function of temperature, it was possible to derive equations for the two model compounds that described fluorescence quantum yield and phosphorescence quantum yield as a function of the pre-exponential factors, activation energies, and temperature. These equations were somewhat complex, but some fundamental conclusions were revealed after a few simplifying assumptions were made.
