Kinetics of excitation in TL and OSL detectors

Abstract Kinetic equations for the semi-localized transitions (SLT) model are presented describing charge carrier’s kinetics for the excitation and fast relaxation stages. The formulation allows for dose dependence studies of thermoluminescence (TL) and optically stimulated luminescence (OSL) detectors based on the SLT model. The sets of equations were solved numerically demonstrating temporal evolution of all variables of the SLT model during excitation and fast relaxation. The influence of the dose rate on excitation kinetics is shown.
