Studies On Thermoluminescence Peak Intensities Of Germanium Quantum Dots

In this project work I studied the TL properties of germanium Quantum dots in thernone trap one recombination model for fist order kinetics. I simulated the TL glowrncurve for different parameters like the activation energy, the frequency factor, thernheating rate and the initial concentration of the electrons in the conduction bands.rnThe result shows that as the activation energy E is increased, the TL glow curve shiftsrntowards higher temperatures, but the curve maintains its overall shape. Moreover,rnthe initial concentration of filled traps has no effects on both the maximum height ofrnthe TL glow curve and the temperature of maximum TL intensity Tmax, but leaves thernoverall shape unchanged in the case of the Garlick-Gibson model and May-Partridgernmodel. I also showed that as the frequency factor s is increased, the TL glow curvernshifts towards lower temperatures, but the curve maintains its overall shape for thernthree models. At the same time the effect of initial concentration of filled traps studiedrnand showed that the initial concentration has no effects on the maximum height ofrnthe TL glow curve, and leaves the shape of TL glow curve unchanged.
