Preliminary TL and OSL investigations of obsidian samples
Polymeris, George S.; Gogou, D.; Afouxenidis, Dimitrios; Rapti, S.; Tsirliganis, Nestor C.; Kitis, George (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 ... -
Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
Polymeris, George S.; Afouxenidis, Dimitrios; Raptis, Spyridoula; Liritzis, Ioannis; Tsirliganis, Nestor C.; Kitis, George (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, ... -
Thermal quenching of thermoluminescence in quartz samples of various origin
Subedi, Bhagawan; Oniya, Ebenezer O.; Polymeris, George S.; Afouxenidis, Dimitrios; Tsirliganis, Nestor C.; Kitis, George (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 ... -
Thermal quenching of thermoluminescence in quartz samples of various origins
Subedi, Bhagawan; Afouxenidis, Dimitrios; Polymeris, George S.; Bakoglidis, Konstantinos D.; Raptis, Spyridoula; Tsirliganis, Nestor C.; Kitis, George (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 ... -
Thermally assisted OSL from deep traps in Al2O3:C
Polymeris, George S.; Raptis, Spyridoula; Afouxenidis, Dimitrios; Tsirliganis, Nestor C.; Kitis, George (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 ... -
TL and OSL response of turquoise for dosimetric application
Subedi, Bhagawan; Afouxenidis, Dimitrios; Polymeris, George S.; Tsirliganis, Nestor C.; Paraskevopoulos, Konstantinos M.; Kitis, George (University of Aegean, 2010)Turquoise is one of the amongst first gem stones used in jewelry and possessing cultural value since 2000 BC (at least). This work attempts characterize this stone scientifically using both thermally (TL) and optically ...
