Thermal quenching of thermoluminescence in quartz samples of various origin
(Elsevier Science BV, 2011-03-15)
The effect of thermal quenching stands among the most important properties in the thermoluminescence (TL) of quartz on which many applications of TL are based. Since the quartz samples used in various applications are all ...
Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
(Pergamon-Elsevier Science Ltd, 2011-10)
Knowledge of the relative luminescence response to alpha and beta radiation is very important in TL and OSL dating. In the present study the relative alpha to beta response is studied in a sedimentary quartz sample, ...
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
(IOP Publishing Ltd, 2011-10-05)
The formation of a carbonated hydroxyapatite (HCAp) layer on the surface of bioactive materials is the main reaction that takes place upon their immersion in physiological fluids. To date, all techniques used for the ...
Equivalent dose in quartz from young samples using the SAR protocol and the effect of preheat temperature
(Pergamon-Elsevier Science Ltd, 2006-09)
Major concerns in the dating of samples younger than a few hundred years by the optically stimulated luminescence (OSL) technique are thermal transfer and partial bleaching. Thermal transfer during preheating enhances the ...
Thermoluminescence and optically stimulated luminescence properties of natural barytes
(Elsevier Ltd, 2010-12)
Heavy, baryte-loaded, concrete is commonly used as radiation shielding material around high energy particle accelerators. Concrete samples received from a shielding block located at CERN cite contain many crystalline ...
Component-resolved thermal stability and recuperation study of the LM-OSL curves of four sedimentary quartz samples
(Elsevier Ltd, 2007-09)
Thermal stability as well as recuperation stands among the crucial general characteristics of different OSL components in quartz. Through a series of thermal stability and recuperation experiments, in conjunction with curve ...
Component resolved OSL dose response and sensitization of various sedimentary quartz samples
(Elsevier Ltd, 2007-02)
The structure of the linearly modulated optically stimulated luminescence (LM-OSL) signal was studied for four sedimentary quartz samples, collected from different sites around Istanbul, Turkey. Applying a computerized ...
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)
The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ...
Investigation of OSL signals from very deep traps in unfired and fired quartz samples
(Elsevier Science BV, 2010-03-15)
This paper presents an attempt to isolate experimentally optically stimulated luminescence (OSL) signals which may originate from very deep traps (VDT) in quartz samples. As VDT we consider those traps which are responsible ...
TL/OSL properties of crystalline inclusions from heavy, barytes loaded, concrete
(Pergamon-Elsevier Science Ltd, 2010-03)
In the present work, we report the luminescence data obtained from heavy, barytes loaded, concrete containing many crystalline inclusions, extracted from a shielding block located at CERN. The use of both Thermoluminescence ...
