Abstract A newly developed copper, lithium, and potassium-activated magnesium oxide (MgO:Cu0.001%,Li10%,K10%) using solution combustion synthesis (SCS) method is shown to have promise as a thermoluminescence material. Its sensitivity, dose dependence, spectral distribution of radioluminescence (RL) emission, glow curve characteristics and storage stability are found as all favorable for dosimetric purposes. The structural characterization and phase composition were checked using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Microcrystals of MgO:Cu,Li,K were obtained by sintering material at 1200 oC for 4 h with a mean size of ∼450 nm. RL studies showed that the energy traps in the samples are closely associated with two emission bands located at ∼750 nm (dominant) and between 320 and 500 nm. It was determined that the TL signals from the stable TL peaks at 214 and 285 °C decreased around 6% after 4 weeks of dark storage. The kinetic parameters were determined with the computerized glow curve deconvolution (CGCD) and initial rise (IRM) methods.

摘要 使用溶液燃烧合成 (SCS) 方法新开发的铜、锂和钾活化的氧化镁 (MgO:Cu0.001%,Li10%,K10%) 被证明具有作为热致发光材料的前景。发现其灵敏度、剂量依赖性、辐射发光 (RL) 发射的光谱分布、辉光曲线特性和储存稳定性都对剂量测定目的有利。使用 X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 检查结构表征和相组成。MgO:Cu,Li,K 微晶是通过在 1200 oC 下烧结材料 4 小时获得的，平均尺寸约为 450 nm。RL 研究表明，样品中的能量陷阱与位于~750 nm（主导）和 320 至 500 nm 之间的两个发射带密切相关。经测定，在 214 和 285 °C 的稳定 TL 峰的 TL 信号在暗储存 4 周后下降了约 6%。动力学参数用计算机辉光曲线解卷积 (CGCD) 和初始上升 (IRM) 方法确定。
