Abstract :
New excitation channels of cerium ion for various fluoride crystals Ce/sup 3+/:LiCaAlF/sub 6/ (Ce:LiCAF), Ce/sup 3+/:LiSrAlF/sub 6/ (Ce:LiSAF), and Ce/sup 3+/:LiSr/sub 0.8/Ca/sub 0.2/AlF/sub 6/ (Ce:LiSCAF) are observed. These excitation channels coincide with the bandgap of each respective crystal.
