We have simulated the change in exciton distribution and fluorescence from a crystal surface, using an anthracene single crystal irradiated by an N_2 laser pulse. The change in the excition distribution in the sample is considered to occur by three processes. These are natural decay, exciton diffusion, and the reabsorption effect. The exciton distribution becomes uniform as time passes after irradiation. The results of the simulation agree fairly well with the experimental results on decay times at typical wavelengths of fluorescence and time-resolved fluorescence spectra. It is also confirmed that the time dependence of the reabsorption effect depends on the change in exciton distribution.
