The 110°C Thermoluminescence peak as a probe in bioactivity study of the 58S sol-gel bioactive glass
(Trans Tech, 2011-11-06)
Results of the present study provide strong indications towards the effective application of the 110°C Thermoluminescence (TL) peak in discriminating between different bioactive responses for the case of the 58S bioactive ...
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 ...
Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
(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
(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 ...
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 ...
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 ...
IRSL dating of a deep water core from Pylos, Greece; comparison to post ir blue osl and tl dating results
(UNIV AGEAN, 2011)
The 'double SAR' protocol procedure permits the determination of two equivalent dose (De) values for each polymineral aliquot; an IRSL De resulting mostly from feldspars along with a post-IR OSL De for a mixed signal for ...
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 ...
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(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 ...
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 ...
