Photoluminescence, scintillation and thermoluminescence properties of undoped and Ce-doped SrLaAl₃O₇ crystals grown using the optical Floating Zone technique were examined. An intense broad emission peak at 400 nm are observed from photoluminescence excitation-emission maps and scintillation spectra of the Ce-doped SrLaAl₃O₇ crystals, with the origin is ascribed to the 5d-4f transitions of Ce³⁺. The primary decay of the Ce-doped and undoped SrLaAl₃O₇ crystals are attributable to the Ce³⁺ ions and intrinsic luminescence, respectively. The 3.0% Ce-doped SrLaAl₃O₇ crystal shows the highest light yield of 760 ph/5.5 MeV-α among the investigated samples based on pulse height analysis under α-rays excitation from ²⁴¹Am.

研究了使用光学浮区技术生长的未掺杂和Ce掺杂的SrLaAl ₃ O ₇晶体的光致发光，闪烁和热致发光特性。从掺杂Ce的SrLaAl ₃ O ₇晶体的光致发光激发-发射图和闪烁光谱观察到400nm处的强烈的宽发射峰，其起源归因于Ce ³⁺的5d-4f跃迁。掺杂Ce和未掺杂SrLaAl ₃ O ₇晶体的主要衰变分别归因于Ce ³⁺离子和固有发光。3.0％Ce掺杂SrLaAl ₃ O ₇在²⁴¹ Am的α射线激发下，基于脉冲高度分析，在所研究的样品中，该晶体显示出最高的760 ph / 5.5MeV-α光产率。
