The time dependence of an excitonic luminescence is measured in anthracenecrystals in the picosecond regime at room temperature. The luminescence rise time iswithin the detection limit at any observation energy. The luminescence decays non-ax-ponentially. The fast decay component, whose decay time is about 0.8 ns, is observedfor the luminescence in the strong absorption region. In the weak absorption region,the decay time is larger than 10 ns. Such a rernarkable energy-dependence of thedecay time is interpreted by taking account of the luminescence reabsorption and theregeneration of excitons. The true radiative decay-time of exeitons is determined to be0.8 * 0.1 ns which is about one tenth of that determined in the nanosecond regime.
