摘要：

The lithium magnesium molybdate Li2-2xMg2+x (MoO4)(3): xYb(3+) (x= 0.01, 0.03, 0.05 and 0.07) phosphors were prepared by combustion synthesis method at 750 degrees C. The phases of prepared phosphors were confirmed by X-ray diffraction pattern and luminescent properties of phosphor materials were systematically studied. Li2Mg2(MoO4)(3) has an orthorhombic symmetry and has discovered a three-dimensional framework consisting of metal-oxygen octahedra and trigonal prisms (where Li and Mg reside) that are interconnected by Moth tetrahedra. As a result of host absorption of Li2Mg2(MoO4)(3), a broad excitation band ranging from 200 to 400 nm is recorded when Yb3+ emission was observed, photoluminescence spectra measured suggests the efficient energy transfer from host to Yb3+ ions. Upon ultraviolet excitation, an intense near-infrared emission of Yb3+ (F-2(5/2) -> F-2(7/2)) around 986 nm is observed in Li2Mg2(MoO4)(3): Yb3+. All the results indicate that Yb3+ doped Li2Mg2(MoO4)(3) crystal can serve as UV excited phosphor that is a promising candidate as an associated application for the tunable laser.
