Thermoluminescence characteristics of Cu2O doped Calcium Lithium borate glass irradiated with the cobalt-60 gamma rays

The aim of this study is to prepare and investigate the thermoluminescence characteristics for the un-doped and Cu2O doped calcium lithium borate glass upon adding various Cu2O concentrations of 0.005% to 0.1 mol%. The glasses were prepared by melt quenching method and irradiated with 60CO gamma-ray having different doses in the range of (0.5-4) Gy, (5-10) Gy, and (20-100) Gy. The amorphous phases were identified for optimization glass samples, effect of heating rate, glowing curves, linearity, sensitivity, fading, reproducibility of response and minimum detectable dose are also studied. The TL sample with 0.02 mol% Cu2O concentration has higher response compared to the other samples concentration for a delivered dose of 50 Gy, The recorded glow curves consist a dominant peak at 187 °C for a heating rate of 5 °C s−1. However, the value of effective atomic number Zeff is 8.84 for 0.02Cu2O doped which are near to the atomic number of soft tissue.
