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 and optically stimulated luminescence properties of natural barytes
Kitis, George; Güneç Kıyak, Nafiye; Polymeris, George S. (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 ... -
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 ... -
TL/OSL properties of crystalline inclusions from heavy, barytes loaded, concrete
Güneç Kıyak, Nafiye; Polymeris, George S.; Kitis, George (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 ...
