Abstract
Well-known wavelength-dependent decay time of exciton luminescence is interpreted in a model based on exciton diffusion and reabsorption of the short wavelength of the luminescence spectrum. The decay curves of the singlet-exciton luminescence in anthracene, depending on wavelength, experimental geometry and penetration depth of incident light, are simulated very well by the model.
