BaEMg(BOa)2:Ce^3+,Eu^2+,Na^+: A potential single-phased two colour borate phosphor for white light-emitting diodes
A two colour phosphor Ba2Mg(BO3)2:Ce^3+,Eu^2+,Na^+ was synthesized using solid-state reaction method. Luminescence of Ba2Mg(BO3)2:Ce^3+,Eu^2+,Na^+ showed 416 and 618 nm emission bands attributed to Ce^3+ and Eu^2+ emission, respectively. Energy transfer occurred from Ce^3+ to Eu^2+ through a signifi...

description | A two colour phosphor Ba2Mg(BO3)2:Ce^3+,Eu^2+,Na^+ was synthesized using solid-state reaction method. Luminescence of Ba2Mg(BO3)2:Ce^3+,Eu^2+,Na^+ showed 416 and 618 nm emission bands attributed to Ce^3+ and Eu^2+ emission, respectively. Energy transfer occurred from Ce^3+ to Eu^2+ through a significant overlap of Eu^2+ excitation spectrum with Ce^3+ emission spectum in Ba2Mg(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):Ce^3+,Eu^2+,Na^+ phosphor showed potential application for white light-emitting diodes (LEDs). |
