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 ...
Reconstruction of thermally quenched glow curves in quartz
(Pergamon-Elsevier Science Ltd, 2012-04)
The experimentally measured thermoluminescence (TL) glow curves of quartz samples are influenced by the presence of the thermal quenching effect, which involves a variation of the luminescence efficiency as a function of ...
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 ...
In-homogeneity in the pre-dose sensitization of the 110 degrees C TL peak in various quartz samples: The influence of annealing
(Elsevier Science BV, 2012-03-01)
The pre-dose sensitization effect of the 110 degrees C TL glow-peak of quartz is a basic tool in thermoluminescence and optically stimulated luminescence dating and retrospective dosimetry. In the present work, a homogeneity ...
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 ...
Investigating the thermally transferred optically stimulated luminescence source trap in fired geological quartz
(Pergamon-Elsevier Science Ltd, 2014-03)
The pre-dosed thermoluminescence (TL) emission of quartz has been found to be useful in retrospective dosimetry and archaeometry. Though the pre-dosed optically stimulated luminescence (OSL) and emissions have been reported ...
A comparative morphological, compositional and tl study of tenedos (Bozcaada) and Sile aeolianites, Turkey
(Univ Agean, 2012)
Aeolianites are carbonate-cemented deposits of coastal dune sands, mostly of Quaternary age. Even though aeolianite exposures on the coasts of the Mediterranean Sea are frequent, very few records have been documented from ...
Thermal quenching of thermoluminescence in quartz samples of various origins
(Univ Agean, Dept Mediterranean Stud, 2010)
The effect of thermal quenching plays an important role in the thermoluminescence (TL) of quartz on which many applications of TL are based. In present work it is investigated that the thermal quenching parameters i.e. the ...
Investigation of the OSL signal from very deep traps in natural quartz
(Univ Agean, Dept Mediterranean Stud, 2010)
It has been recently reported by several studies that a thermally transferred optically stimulated luminescence (TT-OSL) signal from quartz grains can be used to extend the dating range for quartz samples. The TT-OSL signals ...
Preliminary TL and OSL investigations of obsidian samples
(Univ Agean, Dept Mediterranean Stud, 2010)
Obsidian is a volcaniclastic mineral extremely hard to break, which was used in prehistoric Greece (and elsewhere in the World), in order to provide tools, weapons, knives and arrowheads. The present work aims to characterize ...
