The effect of sodium as a co-dopant on the thermoluminescence (TL) properties of copper-doped zinc lithium borate (ZLB: Cu) subjected to Co-60 gamma radiation is reported in this study. TL intensity is enhanced with the introduction of sodium in ZLB: Cu. The obtained glow curve is simple with a single peak. The annealing procedure and the best heating rate for the proposed thermoluminescent dosimeter (TLD) are established, and the phosphor is reusable. The TL response within the dose range of 0.5-1000Gy is investigated. The results show that the thermal fading behaviour is improved significantly.
本研究报道了钠作为共掺杂剂对经Co-60γ辐射的铜掺杂硼酸锌锂（ZLB:Cu）热释光（TL）性能的影响。在ZLB:Cu中引入钠后，热释光强度增强。所获得的发光曲线很简单，只有一个峰。确定了所提出的热释光剂量计（TLD）的退火程序和最佳加热速率，并且该磷光体可重复使用。研究了0.5-1000Gy剂量范围内的热释光响应。结果表明，热衰退行为得到了显著改善。
