Abstract

Abstract We have used Electron Spin Resonance (ESR), Thermoluminescence (TL) and Infra-Red Absorption Spectroscopy (IR) to monitor a variety of defects, in samples of both synthetic and natural, crystalline quartz, as a function of various annealing and sweeping treatments. We have attempted to establish correlations between the various defects and the production of TL in this material in the region of 100°C. This TL peak is known as the “Pre-dose” peak because of its property of increasing in size following combined irradiation and annealing treatments. The data presented in this work demonstrate the involvement of the (AlO4)0 center and suggest that H (probably in the form of H+ ions) is also intimately involved in the TL production process.
