I simulated the TL glow curve for different parameters like the activation energy, the frequency factor, the heating rate and the initial concentration of the electrons in the conduction bands. The result shows that as the activation energy E is increased, the TL glow curve shifts towards higher temperatures, but the curve maintains its overall shape. Moreover, the initial concentration of filled traps has no effects on both the maximum height of the TL glow curve and the temperature of maximum TL intensity Tmax, but leaves the overall shape unchanged in the case of the Garlick-Gibson model and May-Partridge model. I also showed that as the frequency factor s is increased, the TL glow curve shifts towards lower temperatures, but the curve maintains its overall shape for the three models. At the same time the effect of initial concentration of filled traps studied and showed that the initial concentration has no effects on the maximum height of the TL glow curve, and leaves the shape of TL glow curve unchanged.enStudiesThermoluminescencePeak IntensitiesGermaniumQuantum DotsThesis
