Abstract We evaluated photoluminescence (PL) and scintillation properties of TeO2–Al2O3-WO3 glasses with different concentrations of Nd (0, 0.1, 0.5 and 1.0 mol.%). The glass samples were fabricated by the conventional melt-quenching method. The Nd-doped samples showed sharp emission peaks due to the 4f-4f transitions of Nd3+ in PL and scintillation. The 0.5% and 1.0% Nd-doped samples showed high PL quantum efficiencies and scintillation intensities among the sample tested. Furthermore, the decay time constants for the Nd-doped samples in PL and scintillation were 140–206 and 110–123 μs, respectively. In addition, the undoped and Nd-doped samples showed thermally stimulated luminescence (TSL) with a weak glow peak approximately at 285 °C, and the detection limit of TSL (10 Gy) was much higher than that of common TSL materials.

Nd掺杂TeO2-Al2O3-WO3玻璃的闪烁和TSL特性

摘要 我们评估了具有不同 Nd 浓度（0、0.1、0.5 和 1.0 mol.%）的 TeO2-Al2O3-WO3 玻璃的光致发光 (PL) 和闪烁特性。玻璃样品是通过传统的熔融淬火方法制造的。由于 PL 和闪烁中 Nd3+ 的 4f-4f 跃迁，Nd 掺杂样品显示出尖锐的发射峰。0.5% 和 1.0% Nd 掺杂的样品在测试的样品中显示出高 PL 量子效率和闪烁强度。此外，PL 和闪烁中 Nd 掺杂样品的衰减时间常数分别为 140-206 和 110-123 μs。此外，未掺杂和掺杂 Nd 的样品显示出热激发发光 (TSL)，在大约 285°C 处有一个微弱的辉光峰，TSL 的检测限 (10 Gy) 远高于普通 TSL 材料的检测限。
