• Fluorescence and phosphorescence have been observed in a naphthalenedoped crystal of durene. Measured fluorescence spectra at various conditions show a transfer of excitation energy from durene to naphthalene molecules and a build-up of a new green band by irradiation of shorter ultra-violet light. Phosphorescence spectra and decays show that phosphorescence is due to a transition from a triplet state to a ground state in a naphthalene molecule. Two decay times have been observed, a larger one belonging to an ordinary triplet state and a smaller one belonging to a triplet state coupled with a newly introduced center emitting a green band. An energy level scheme in the crystal is presumed .
