Effects of Annealing on Thermoluminescence Peak Positions and Trap Depths of Synthetic and Natural Quartz by Means of the Various Heating Rate Method

Abstract

Some environmental and experimental variables such as annealing process alter the structure of glow curves of some thermoluminescence materials. We investigate the effects of annnealing on thermoluminescence peaks of synthetic and natural quartz at different heating rates. The experimental results show that the peak temperatures of glow peaks in annealed samples shift to higher temperature sides. The amount of shifting is higher for low temperature peaks than high temperature peaks. The trap depths of annealed and unannealed samples of both synthetic and natural quartz are also obtained by various heating rate methods. It is noted that the annealing process affects the trap depth of all glow peaks and the trap depth increases after the annealing process.
