Non-radiative transitions are one of the important problems for the thermoluminescence event. One of the models offered to explain non-radiative transition is Schön-Klasens. In this paper, the Schön-Klasens model was discussed both from theoretical and numerical viewpoints. The brief information about mathematical principals of the model was given and differential equations that controlled charge carrier traffic were derived. Some numerical solutions of the model were performed by using variable Ee and Eh parameters. This study has concluded that the glow curve is affected by both charge carriers according to relationship between Ee and Eh parameters.
