Abstract We have investigated doping concentration dependence of optically-stimulated luminescence (OSL), as well as the fundamental optical and thermally-stimulated luminescence (TSL), in Eu-doped CsBr transparent ceramics. The photoluminescence, TSL and OSL showed a broad emission spectrum peaking around 440 nm, and the emission origin was the 5d-4f transitions of Eu2+. The emission peak position shifted to longer wavelength with increasing the concentrations of Eu. For OSL, the dose measurement sensitivity was confirmed to be as low as 0.01 mGy when the doping concentration of Eu was 0.3–1.0%; therefore, the optimal concentration of Eu was determined to be 0.3–1.0%.

掺杂不同浓度 Eu 的 SPS 衍生的 CsBr 透明陶瓷的 TSL 和 OSL 特性

摘要 我们研究了掺 Eu 的 CsBr 透明陶瓷中的光学激发发光 (OSL) 以及基本光学和热激发发光 (TSL) 的掺杂浓度依赖性。光致发光、TSL 和 OSL 显示出在 440 nm 附近达到峰值的宽发射光谱，发射源是 Eu2+ 的 5d-4f 跃迁。随着 Eu 浓度的增加，发射峰位置向更长的波长移动。对于 OSL，当 Eu 的掺杂浓度为 0.3-1.0% 时，剂量测量灵敏度被证实低至 0.01 mGy；因此，Eu 的最佳浓度被确定为 0.3-1.0%。
