Abstract Undoped and Tb-doped MgAl2O4 transparent ceramics were synthesized by the Spark Plasma Sintering (SPS) method, and dosimetric properties were investigated. The Tb-doped sample showed thermally stimulated luminescence (TSL) and optically stimulated luminescence (OSL), in which the emission center was Tb3+ ions. The TSL glow peaks of the Tb-doped sample are detected at 64, 151, 235, 299, and 385 °C. The Tb-doped sample had a linear TSL response in a dose range from 0.01 to 1000 mGy.

未掺杂和掺 Tb MgAl2O4 透明陶瓷的剂量学特性

摘要 采用火花等离子烧结（SPS）法合成了未掺杂和掺铊的MgAl2O4透明陶瓷，并研究了剂量学特性。Tb 掺杂的样品显示出热激发光 (TSL) 和光激发光 (OSL)，其中发射中心是 Tb3+ 离子。在 64、151、235、299 和 385 °C 下检测到 Tb 掺杂样品的 TSL 辉光峰。Tb 掺杂样品在 0.01 至 1000 mGy 的剂量范围内具有线性 TSL 响应。
