Understanding the complex nature of luminescent characteristics of quartz requires adequate knowledge of charge trafficking among electron and hole traps during excitation and stimulation of materials. These quantities, which are difficult to measure and mostly studied through modelling and theoretical approaches, influence the charge trafficking among the traps. This study aimed at employing a designed TL sequence, with a focus on reservoirs and competitors, to study factors affecting the shape of thermal activation curve/characteristics (TACs) of the 110 °C TL glow peak of quartz. The materials under investigations were two quartz samples from Nigeria that were annealed at 800 °C for 1 h. The results showed the structure of the TAC to be related to the nature of the glow curves (in particular high peaks) obtained during the thermal activation. The roles of reservoirs and competitors in luminescence characteristics have been used to explain the property of the 110 °C TL peak of two quartz samples in the present study. This report is among the first experimental attempts to monitor effects directly correlated to the presence of these concepts.
