Dose-rate effect in the model of semi-localized transitions (SLT)

The model of semi-localized transitions (SLT) unifies two standard models of thermoluminescence (TL) and optically stimulated luminescence (OSL) kinetics - the simple trap model (STM) and the model of localized transitions (LT). SLT equations were previously formulated for the heating stage of TL. This paper presents SLT equations for the excitation and fast relaxation stages. Exemplary calculations were performed to show the occurrence of dose-rate effect - previously found in STM. It is shown that the dose-rate effect occurs for both - localized and delocalized TL glow peaks.
