“…Franklin et al (1995), have shown the presence of at least four of the quartz's TL peaks, namely at 95-110, 150-180, 200-220 as well as 305-325°C, depending on the heating rate. Similar results were also reported by other authors, such as Ogundare et al (2006), Koul (2008) and Preusser et al (2009). Additional glow peaks are also available in the literature for different quartz samples as well as different detection optics, such as at 250-270°C as well as the one at 350-375°C (Wintle, 1997;Thomsen, 2004).…”

Abstract:In the present work the sensitization of the entire glow-curve is studied in 6 different quartz samples of Nigerian origin. The investigation was applied to the un-fired "as is" samples as well as to samples fired at 900°C for 1 hour following cooling to room temperature. The results showed that in the case of "as is" glow-curve is sensitized as a whole. There is an abrupt transition from the "natural" sensitivity without any previous heating and the artificial sensitivity induced after the first heating. The sensitization is growing up strongly to the 10 th heating but to a lower rate. The sensitization factor of the TL glow-peak at "110°C" was found to be linearly correlated to the higher temperature TL peaks. In the case of annealed samples there is an initial increase between the sensitivity immediately after the end of annealing and after the first heating. As the number of heating is increased up to the 10 th heating the sensitization is stabilized at a constant value. The results are discussed in the framework of existing models and implications of the sensitization effect in various applications, while some explanations are attempted.

“…Quartz of different origins have associated glow peaks ranging from 95-110, 150-180, 200-220 as well as 305-325°C, depending on the heating rate used. Similar results, but not exact, are also available in the literature for different quartz samples as well as different detection optics [17,21,28,34,36]. The influence of excitation dose and thermal treatment on the TL properties of glow peaks in quartz is widely studied [17,21,24].…”

Mechanism of the experimentally observed anomalous shift of a thermoluminescence (TL) glow peak that varied with irradiation dose is yet to be fully established. A theory that the anomalous peak must have contained more than one first order composite peaks each with different TL dose characteristics has been one major explanation proposed to explain this observation. This work was undertaken to simulate the anomalous glow peak by using a modified version of a previously proposed model and numerically solving sets of simultaneous differential equations governing the stages of TL phenomena (excitation, relaxation and heating). In the modified model, two additional electron trapping centers were incorporated in order to simulate accurately this glow curve. Computerized glow curve deconvolution (CGCD) analyses was carried out on the simulated glow peak in attempt to retrieve back the electron trapping center energies and to identify their respective peak positions. The outcome of this confirmed the peak to be possibly composite in nature comprising of three overlapping glow peaks at 288, 300 and 317 o C with respective energy gaps of 1.70, 1.73 and 1.75eV. It is therefore further substantiated that this kind of temperature shift of peak with dose resulting from composite glow peaks is possible.

“…It must be recognized here that the prime cause for the pre-dose phenomenon is the accumulation of the charge in the R-centres in nature (Koul 2008). The firing episode removes all the holes from these centres in the case of ceramics.…”

The evolution of novel procedures for the evaluation of equivalent dose using the optically stimulated luminescence (OSL) signal of quartz became necessary to address (i) the sensitization experienced by the signal during the pre-heat treatment and (ii) the in situ sensitization occurring in nature. The pre-dose phenomena of the OSL and 110 °C TL pre-dose emissions have been reported to be similar. In light of this observation, an attempt has been made in this paper to visualize the role of R-centres in the sensitization process of the OSL emission. The results, based on the experimental observations and kinetics considerations of R-centres, confirm that the R-centres participate in the sensitization process of this signal.
