The model of the cathodoluminescence decay of the YAG:Ce characteristic luminescence band (center at 550 nm) is presented. This kinetics model is based on only two states, one trap (oxygen vacancy state) and one luminescence center (cerium ion in our case). In this model, it is assumed that the activation energy of the trapped states varies slightly due to presence of the local environment.
