Abstract

CeSO4Cl: Dy phosphor is prepared by wet chemical method. The thermoluminescence (TL) study of CeSO4Cl:Dy phosphor has been presented in this paper. The strong sensitivity of the CeSO4Cl: Dy phosphor is obtained with the broadness of the glow peak for various concentrations of Dy and different γ-rays doses. The phosphors CeSO4Cl: Dy has a simple TL glow curve structure with a single prominent peak at around the temperature 169°C indicating single trapping sites. The phosphor may be quite suitable for use in dosimetry of ionizing radiations.
