Abstract

This study investigates the thermoluminescence (TL) properties of copper (Cu2O) doped lithium magnesium borate (LMB) glass co-doped with strontium (SrO) subjected to Co-60 gamma irradiation. The glass samples based on (69.95-x)B2O3 – 20Li2O – 10MgO: 0.05Cu2O; xSrO, where 0.001 ≤ x ≤ 0.03 mol% were prepared by melt-quenching technique. The amorphous state of both Sr co-doped and Cu-doped LMB glass samples were confirmed by using X-Ray Diffraction (XRD). For this study, the optimum TL Response was found with 0.003 mol% of Sr concentration with TL intensity 3.6 x 105 nCg-1. The maximum peak temperature of glow curve for all glass samples was observed at 170-200 oC. The annealing procedure for the studied samples was determined at 100 oC for 20 minutes with the heating rate of 7 oC s-1.
