Abstract The Frisch‐Collins diffusion theory, developed to handle the case of a plurality of competing traps in the diffusion field, is used to calculate the time dependence of the fluorescence both from host crystal and impurity trap in a doped organic solid. Satisfactory agreement is found between experiment and theory indicating that a theory of exciton diffusion can account for the excitation energy transfer in an organic crystal.
