Abstract

BaSO4: Dy samples for different doping concentrations have been synthesized by co-precipitation methods. TL glow curves of BaSO4: Dy samples after irradiation with γ-rays have been recorded. The observed TL glow curves show a complex curve consisting of two sharp peaks at Tm= (385–393) K, (436–445) K and a daughter peak at Tm(405–410) K respectively. Trapping parameters of the TL glow curves are also evaluated using CGCD technique.
