Abstract
Copper doped zinc lithium borate glass was prepared by solid state melt quenching method and characterized using X-ray diffractometry. The effect of varying concentration of dopant CuO on thermoluminescence (TL) properties of zinc lithium borate is reported in this paper. The best annealing temperature and time were found to be 300 °C and 30 min respectively. While the optimal heating rate was 3 °C. Glow curves with single peaks for all concentrations were obtained. The TL intensity increases with the increase of dopant concentration and radiation dose from 0.5 to 4 Gy. Time-base thermal fading was stable. Attractive reusability and kinetic parameters of the phosphor were also achieved. These outstanding features show that our dosimeter has the potential ability to use for radiation processing dosimetry.
