We investigate the spectra and scintillation properties of Ce:YA103,Ce:Y_3Al_5O_(12),and Ce:LaA103.For Ce:YAlO_3,the excitation spectrum is very similar with the absorption spectrum;for Ce:Y_3Al_5O_(12) and Ce:LaAlO_3,the excitation spectra are different from the absorption spectra.Further,Ce:YAlO_3 has better scintillation performance than Ce:Y_3Al_5O_(12) whereas Ce:LaAlO_3 has not demonstrated scintillation performance to date.We also provide reasonable explanations for these experimental phenomena from the viewpoint of energy level structure.
We investigate the spectra and scintillation properties of Ce: YA103, Ce: Y_3Al_5O_ (12), and Ce: LaA103.For Ce: YAlO_3, the excitation spectrum is very similar to the absorption spectrum; Ce for Y_3Al_5O_ (12) and Ce: LaAlO_3, the excitation spectra are different from the absorption spectra. Further, Ce: YAlO_3 has better scintillation performance than Ce: Y_3Al_5O_ (12) and Ce: LaAlO_3 has not demonstrated scintillation performance to date. We also provide for rational explanations for these experimental phenomena from the viewpoint of energy level structure.
