Abstract

We investigate the spectra and scintillation properties of Ce:YAlO<sub>3</sub>, Ce:Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>, and Ce:LaAlO<sub>3</sub>. For Ce:YAlO<sub>3</sub>, the excitation spectrum is very similar with the absorption spectrum; for Ce:Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub> and Ce:LaAlO<sub>3</sub>, the excitation spectra are different from the absorption spectra. Further, Ce:YAlO<sub>3</sub> has better scintillation performance than Ce:Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>; whereas Ce:LaAlO<sub>3</sub> has not demonstrated scintillation performance to date. We also provide reasonable explanations for these experimental phenomena from the viewpoint of energy level structure.
