title: Synthesis and photoluminescence of novel Ba9Y2Si6O24:Eu2+ green phosphor.
abstract: Novel (Ba1_xEu(x))9Y2Si6O24 green phosphors were successfully prepared by a solid-state reaction method. The prepared (Ba1_xEu(x))9Y2Si6O24 green phosphors showed a single intense broadband emission in a range from 502 to 510 nm. The effects of the Eu2+ doping concentration on the optical properties were discussed under consideration of concentration quenching. The experimental results clearly indicates that the prepared (Ba1_xEu(x))9Y2Si6O24 green phosphors have great potentials as a down-conversion green phosphor for white light emitting diodes (LEDs) utilizing blue LEDs as the primary light source.
