摘要：The new apatite-silicate phosphor doped with Eu ions in Ba-10(PO4)(4)(SiO4)(2) matrix was synthesized through solid-state reaction. It was found that the as-synthesized phosphor displayed apparent mixture of band and line emission peaks giving rise to pseudo white light. The narrow emission bands peaking at 410 nm can be assigned to the 4f(6)5d -> 4f(7)(S-8(7/2)) transition of Eu2+ ions, and the other band at 507 nm is ascribed to anomalous fluorescent emission. One group of line emission peaking at 595 nm and 613 m were due to the D-5(0) -> F-7(1) and D-5(0) -> F-7(2) transition of Eu3+ ions. The occurrence of photostimulated luminescence and discrete emission lines in violet (410 nm), green (507 nm) and red (595 nm and 613 nm) colors indicate that this material has potential application in fields of white-light-emitting.
