Effect of strontium concentration on thermoluminescence glow curve of copper doped lithium magnesium borate glass
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 p...

| Summary: | 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. |
