Optically stimulated luminescence from quartz measured using the linear modulation technique

Component-resolved thermal stability and recuperation study of the LM-OSL curves of four sedimentary quartz samples

“…The behavior of this component is of great interest, since it exhibits a remarkable stability for pre-heat temperatures up to 350 • C and then decreases. The components show thermal patterns similar to those of components A, B, C and D reported by Bulur et al (2000), as well as to those of the fast, medium and slow components reported by Jain et al (2003).…”

“…The process consists of heating the sample to a particular temperature followed by an immediate cooling (Wintle and Murray, 2006). Such experiments were performed by Bulur et al (2000), Li and Chen (2001), Singarayer and Bailey (2003) and Jain et al (2003). Works by both Singarayer and Bailey (2003) and Jain et al (2003) reported an ultra-fast component, which is much less thermally stable than the others, being removed almost completely by heating to 250.280 • C. Therefore, the use of a 10 s pre-heat applied at temperatures between 160 and 260 • C, often used during the procedure of single aliquot regenerative (SAR) protocol (Wintle and Murray, 1998), could effectively remove the ultra-fast component.…”

Exploring the method of optical dating and comparison of optical and 14C ages of Late Weichselian coversands in the southern Netherlands

“…The results possibly can be understood when taking into consideration that the quartz OSL signal consists of various components, each having different characteristics (see e.g. Bailey et al, 1997;Bulur et al, 2000). When constructing the single-aliquot additive-dose growth curve, the most easily stimulated component (the so-called fast component) is being preferentially sampled.…”

Luminescence dating of loess deposits from the Remagen-Schwalbenberg site, Western Germany

“…The net OSL signal of the quartz samples was obtained using the initial 1.0 s of the luminescence signal minus a mean background of the last 5 s for all measurements. To further investigate the quartz OSL characteristics, D e (t) plots (Bailey, 2003;Bailey et al, 2003) were executed for all samples by changing the signal integration interval while the background interval was kept constant to 5 s. Additionally, pulse annealing experiments (180-400°C) using linear modulated OSL (LM OSL, Bulur et al, 2000) were made on samples C-L2896 and C-L2900. The natural OSL signal was reset by OSL stimulation (170°C for 6000 s) in the Risø reader followed by laboratory irradiation (72 Gy).…”
