TL Properties of X-ray Irradiated Li2O-MO-B2O3 (MO=ZnO, CaO, CdO) Glasses Doped with Europium Ions

J. Anjaiah

Abstract: Thermoluminescence (TL) characteristics of X-ray irradiated pure and doped with Eu3+ ions Li2O-MO-B2O3 (MO=ZnO, CaO, CdO) glasses have been studied in the temperature range 303-573K; all the pure glasses have exhibited single TL peak at 382K, 424K and 466 K respectively. When these glasses are doped with Eu3+ ions no additional peaks are observed but the glow peak temperature of the existing glow peak shifted gradually towards higher temperatures with gain in intensity of TL light output. The area under the glow curve is found to be maximum for Eu3+ doped glasses mixed with cadmium oxide as modifier. The trap depth parameters associated with the observed TL peaks have been evaluated using Chens formulae. The possible use of these glasses in radiation dosimetry has been described. The result clearly showed that europium doped cadmium borate glass has a potential to be considered as the thermoluminescence dosimeter.
