摘要：

A series of Sm3+doped Y2MoO6were prepared through high temperature solid state reaction technique. Their phase structures, morphologies and luminescence properties were investigated by X-ray diffraction(XRD), scanning electron microscopy(SEM) and photoluminescence spectrometry. The most intense absorption of Y2MoO6host occurred at 367 nm. Energy transfer from host lattice to Sm3+ions could be observed, and the schematic diagram of energy transfer was constructed. The critical energy transfer distance and energy transfer mechanism between Sm3+ions were discussed in detail. Considering the high color purity and appropriate emission intensity, Sm3+doped Y2MoO6could be a promising phosphor under near ultraviolet light excitation.
