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 ...
Thermally assisted OSL from deep traps in Al2O3:C
(Pergamon-Elsevier Science Ltd, 2010-03)
The present work suggests an alternative experimental method in order to not only measure the signal of the deep traps in Al2O3:C without heating the sample to temperatures greater than 500 degrees C, but also use this ...
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 ...
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 ...
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 ...
Dissolution and subsequent re-crystallization as zeroing mechanism, thermal properties and component resolved dose response of salt (NaCl) for retrospective dosimetry
(Pergamon-Elsevier Science Ltd, 2011-09)
In the present study we report dosimetric properties of iodized salt aiming at using it as an accidental luminescent dosimeter. It was found that the very good sensitivity of its main dosimetric peak is strongly affected ...
Temperature lags of luminescence measurements in a commercial luminescence reader
(Elsevier Science Inc, 2015-09-15)
The temperature recorded in thermoluminescence and optically stimulated luminescence equipments is not the temperature of the sample but that of the heating element on which the thermocouple is attached. Depending upon the ...
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 ...
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 ...
