Reabsorption Effect and Fluorescence Decay Times in Naphthalene Crystals

The reabsorption effect and the kinetics of the fluorescence in the naphthalene crystals were investigated by mean of the nanosecond light pulse method from 80 K to 280 K. The increase of the reabsorption with increasing the temperature was interpreted as being due to the hot-band transition. The temperature dependence of the intrinsic decay times could be explained in term of the vibronically allowed electric dipole transition
