摘要：

A blue-emitting phosphor, Eu2+-activated Mg3Ca3(PO4)(4) phosphor was synthesized by conventional solid-state reaction. X-ray powder diffraction (XRD) analysis confirmed the phase formation. Photoluminescence (PL) results showed that Mg3Ca3(PO4)(4): Eu2+ could be efficiently excited by UV-visible light from 250 to 430 nm, which matched well with the emission wavelengths of near-UV and UV LED chips. The effects of the doped-Eu2+ concentration in Mg3Ca3(PO4)(4): Eu2+ on the PL were also investigated. The result reveals that Mg3Ca3(PO4)(4): Eu2+ is a potential blue-emitting phosphor for white LEDs. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
