As one of the commonly used scintillating materials, single crystals inhibit their further practical applications considering the high cost, limited volume, and time-wasting preparation technique. By the compelling requirement for radiative detection in a variety of fields, numerous novel scintillators have been developed. Here, a novel efficient and transparent Eu3+-doped boroaluminate glass was successfully fabricated by melt-quenching technique. The optical responses to ultraviolet–visible (UV) and X-ray are both significantly enhanced by heavily doping Eu3+ into the glass host. The optimal doping concentration of Eu3+ is 8 mol%. Moreover, the internal quantum yield (IQY) was evaluated to 53.2% with high transparency (83% @ 600 nm). More notably, the best specimen has 18.4% X-ray excited luminescence (XEL) integrated intensity of that of the commercial Bi4Ge3O12 single crystal scintillator. According to our findings, heavily doped boroaluminate glass could be one of the alternative scintillating materials for slow process detection.

用于 X 射线检测的透明重 Eu3+ 掺杂硼铝酸盐玻璃

作为常用的闪烁材料之一,单晶考虑到成本高、体积有限和浪费时间的制备技术,阻碍了它们进一步的实际应用。由于各种领域对辐射检测的迫切要求,已经开发了许多新型闪烁体。在这里,通过熔融淬火技术成功制备了一种新型高效透明的 Eu 3+掺杂硼铝酸盐玻璃。通过将 Eu 3+重掺杂到玻璃基质中,显着增强了对紫外-可见光 (UV) 和 X 射线的光学响应。Eu 3+的最佳掺杂浓度是 8 摩尔%。此外,内部量子产率 (IQY) 评估为 53.2%,具有高透明度(83% @ 600 nm)。更值得注意的是,最好的样品具有 18.4% 的 X 射线激发发光 (XEL) 积分强度,比商用 Bi 4 Ge 3 O 12单晶闪烁体的积分强度高。根据我们的研究结果,重掺杂硼铝酸盐玻璃可能是用于慢速过程检测的替代闪烁材料之一。
