A two colour phosphor Ba 2 Mg(BO3)2:Ce3+,Eu2+,Na+ was synthesized using solid-state reaction method.Luminescence of Ba2Mg(BO3)2:Ce3+,Eu2+,Na+ showed 416 and 618 nm emission bands attributed to Ce3+ and Eu2+ emission, respectively. Energy transfer occurred from Ce3+ to Eu2+ through a significant overlap of Eu 2+ excitation spectrum with Ce3+ emission spectrum in Ba 2 Mg(BO3)2. They also showed that under the excitation of UV radiation, bluish or yellowish white light was generated by coupling a broad blue emission band and a red emission band.By combining with green phosphor, Ba2Mg(BO3 ):Ce3+,Eu2+,Na+ phosphor showed potential application for white light-emitting diodes (LEDs).
