Abstract Undoped and Ce-doped SrLu2O4 single crystals were synthesized by the floating zone method equipped with four Xe lamps, and the photoluminescence (PL) and scintillation properties were investigated. A broad emission band appeared at around 470 nm in PL and scintillation spectra due to the 5d–4f transition of Ce3+. In addition, the PL and scintillation decay time constants were close to typical values of the 5d–4f transition of Ce3+. The pulse height spectra of 137Cs gamma-ray demonstrated that the light yield of undoped and 0.3% Ce-doped SrLu2O4 were 1490 and 570 photons/MeV, respectively. In addition, relationship between gamma-ray energy and photoabsorption peak channel was evaluated.

Ce掺杂的SrLu2O4单晶的光致发光和闪烁特性

摘要 采用四个氙灯的浮区法合成了未掺杂和掺杂Ce的SrLu2O4单晶，并研究了其光致发光（PL）和闪烁特性。由于 Ce3+ 的 5d-4f 跃迁，在 PL 和闪烁光谱中的 470 nm 附近出现了宽发射带。此外，PL 和闪烁衰减时间常数接近 Ce3+ 的 5d-4f 跃迁的典型值。137Cs 伽马射线的脉冲高度谱表明，未掺杂和 0.3% Ce 掺杂的 SrLu2O4 的光产额分别为 1490 和 570 光子/MeV。此外，还评估了伽马射线能量与光吸收峰通道之间的关系。
