- 論文の詳細を見る
Decay curves and spectral shapes of the singlet-exciton luminescence in anthracenecrystals have been studied at room temperature and found to depend on the experimental geometry and on the penetration depth of the exciting light. The well-known wavelength-dependent decay time and time-dependent spectrum occur onlywhen the luminescence is excited in the process of the one-photon absorption and isobserved in the backward-scattering geometry. In the forward-scattering geometry,the decay time is independent of the luminescence wavelength. When the excitons areuniformly generated in the crystal in the process of the two-photon absorption, thewavelength-dependent decay time and time-dependent spectrum do not occur even inthe backward-scattering geometry. These results are interpreted in terms of diffusionof the singlet excitons and reabsorption of the short wavelength photons of the ex-citon luminescence.
