Thermoluminescence of swept and doped irradiated quartz crystals

Thermoluminescence has been used in order to determine which defects are responsible for the glow peaks. Many natural and synthetic samples were submitted to electrodiffusion exchange along the z-axis, or by sodium, or by lithium or by hydrogen ions. Then, an attempt is made to determine both the activation energies of each trap and the lifetime of defects created during irradiation, by using the models which are proposed in the literature. Before recording TL spectra, all samples are irradiated with γ-ray dose until they are saturated. Infrared spectroscopy was used in order to check the effect of all the pretreatments, sweeping and irradiation
