摘要：

Eu3+-activated MgAl(PO4)O:phosphor has been synthesized by a high temperature solid state reaction and efficient red emission under near-ultraviolet excitation is observed. The emission spectrum shows a dominant peak at 594 nm due to the D-5(0) -> F-7(1) transition of Eu3+. The excitation spectrum is coupled well with the emission of UV LED (350-410 nm). The effect of Eu3+ concentration on the luminescent properties of MgAl(PO4)O:Eu3+ and the mechanism of concentration quenching of Eu3+ are studied. The results show that MgAl(PO4)O:Eu3+ is a promising red-emitting phosphor for white LEDs. (c) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
