摘要：

By fixing the trap concentration, the Blumen and Silbey dynamic model for energy migration is applied to ZnS:Mn. We treat trap concentration as independent of Mn concentration for a given ZnS host, and obtain the dependence of both the decay time and intensity on Mn concentration. These correlate with known experimental data, and explain the empirical decay dependence on Mn concentration. We are able to quantify the probability of energy loss to traps using Dexter's equation for dipole-dipole transfer. It is suggested that energy loss to the traps can be influenced by the growth technique. © 1990.
