Abstract

Pr-doped scintillators are attracting attention because of their potential applications in medical devices. In this study, we focused on Pr-doped (La, Y)₂Si₂O₇ scintillators to grow single crystals by the micro-pulling-down method and to evaluate their optical and scintillation properties. From the powder XRD results, the crystal structure and the space group were identified to be monoclinic and P2₁/n, respectively. The results of optical and scintillation characterization show that the luminescence from the Pr³⁺ 5d₁–4f transition increases with increasing Pr³⁺ concentration. The maximum light yield was also obtained for the sample with the highest Pr³⁺ concentration. The Pr-doped (La, Y)₂Si₂O₇ single crystal shows promising properties for application in radiation detection.

掺杂 Pr3+ 的（La, Y）2Si2O7 单晶体的光学和闪烁特性

掺镨闪烁体因其在医疗设备中的潜在应用而备受关注。在本研究中，我们重点研究了掺镨的(La, Y)2Si2O7闪烁体，采用微拉法生长单晶，并评估其光学和闪烁特性。根据粉末 XRD 结果，确定其晶体结构和空间群分别为单斜和 P21/n。光学和闪烁表征结果表明，Pr3+ 5d1-4f 转变的发光随 Pr3+ 浓度的增加而增加。Pr3+浓度最高的样品的光产率也最大。掺杂了 Pr 的（La, Y）2Si2O7 单晶体在辐射探测方面显示出了良好的应用前景。
