In this paper, La1.45Ce0.05Ba3.5(SiO4)1.5(PO4)1.5F compound with apatite structure was synthesized via solid state reaction method. The phosphor exhibits two strong excitation bands at 279nm and 345nm in near ultraviolet light region. When excited at 345nm, the emission peaks of the phosphor give a red-shift from 406nm to 418nm compared with that of 279nm excitation. Besides, the site occupation of...
