摘要	(Zn1-x, Mgx)2GeO4: Mn2+(0x0.25) green phosphors were synthesized by the conventional solid-state reaction, and the effect of Mg incorporation on photoluminescence (PL) and long-lasting phosphorescence (LLP) characteristics of Zn2GeO4: Mn2+was systematically studied. The emission spectrum shows a broad emission band centered at 533 nm, which can be assigned to the4T1(4G)6A1(6S) transitions of Mn2+ion. The emission intensity can be increased by the resonant transfer from a subbandgap state in the host to Mn2+, and the PLE spectra of (Zn1-x, Mgx)2GeO4: Mn2+exhibit a blue shift with the increasing of Mg concentration. Thermoluminescence (TL) spectra indicate that the introduction of Mg into the host deepened the Vo traps, resulting in the enhanced phosphorescence of Mn2+. The possible mechanism of the PL and LLP was discussed based on the PL and TL results. 2017, Science Press. All right reserved.
