我们研究了Ce：YAlO 3、Ce：Y3 Al 5 O 12和Ce：LaAlO 3的光谱和闪烁特性。Ce：YAlO 3的激发光谱与吸收光谱非常相似，Ce：Y3 Al 5 O 12和Ce：LaAlO 3的激发光谱与吸收光谱不同。此外，Ce：YAlO 3具有比Ce：Y3 Al 5 O 12更好的闪烁性能;而Ce：LaAlO 3迄今为止尚未表现出闪烁性能。我们还从能级结构的角度对这些实验现象给出了合理的解释。
We investigate the spectra and scintillation properties of Ce:YAlO3, Ce:Y3Al5O12, and Ce:LaAlO3. For Ce:YAlO3, the excitation spectrum is very similar with the absorption spectrum; for Ce:Y3Al5O12 and Ce:LaAlO3, the excitation spectra are different from the absorption spectra. Further, Ce:YAlO3 has better scintillation performance than Ce:Y3Al5O12; whereas Ce:LaAlO3 has not demonstrated scintillation performance to date. We also provide reasonable explanations for these experimental phenomena from the viewpoint of energy level structure.
