Effects of Ce3+ energy level structure on absorption and luminescence properties

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
