The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
Kitis, George; Güneç Kıyak, Nafiye; Polymeris, George S.; Tsirliganis, Nestor C. (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 ... -
Dating fossil root cast (Black Sea coast, Turkey) using thermoluminescence: Implications for windblown drift of shelf carbonates during MIS 2
Polymeris, George S.; Kitis, George; Güneç Kıyak, Nafiye; Theodosoglou, Eleni; Tsirliganis, Nestor C.; Ertek, Topçu Ahmet; Erginal, Ahmet Evren (Elsevier Ltd., 2016-05-16)Rhizoliths are mostly sub-aerially exposed root prints which appear through removal of the rock units that cap them. A horizontal-lying residual of a rhizolith, consisting purely of soft inner core material of white color ... -
In-homogeneity in the pre-dose sensitization of the 110 degrees C TL peak in various quartz samples: The influence of annealing
Polymeris, George S.; Oniya, Ebenezer O.; Jibiri, Nnamdi N.; Tsirliganis, Nestor C.; Kitis, George (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 ... -
Potassium determinations using sem, faas and xrf: some experimental notes
Liritzis, Ioannis; Mavrikis, D; Zacharias, Nikolaos; Sakalis, Anastasios; Tsirliganis, Nestor C.; Polymeris, George S. (University of Aegean, 2011)The calibration of Scanning Electron Microscopy coupled with Energy Dispersive X-Rays Spectrometry (SEM-EDS) for elemental quantitative analysis is an important task for characterization, provenance and absolute dating ... -
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 ... -
Reconstruction of thermally quenched glow curves in quartz
Subedi, Bhagawan; Polymeris, George S.; Tsirliganis, Nestor C.; Pagonis, Vasilis; Kitis, George (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 ... -
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 ... -
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
Polymeris, George S.; Goudouri, Ourania Menti; Kontonasaki, Eleana; Paraskevopoulos, Konstantinos M.; Tsirliganis, Nestor C.; Kitis, George (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 ... -
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 ...
