以MoO3、Gd2O3及Tb4O7为原料，以NH4HF2为助溶剂，在碳粉还原条件下制备了不同Tb3+掺杂浓度的Gd2(MoO4)荧光粉样品。采用X射线衍射(XRD)对样品的晶体结构进行了表征，发现掺杂浓度的改变未对产物的晶体结构产生影响，产物均为单一正交相Gd2(MoO4)3。对样品的激发、发射光谱及荧光衰减特性进行了测量和分析，结果表明: 样品在200～300 nm范围内具有较强的源自于Tb3+的f-d跃迁及Mo-O电荷迁移跃迁吸收；在紫外光激发下观察到了Tb3+及MoO2-4基团的本征发射。研究了发光强度、荧光寿命以及样品的发光色坐标与Tb3+浓度的关系，结果表明样品的发射光色纯度较差，该体系荧光粉与实际应用要求还有较大差距。

Tb3+ doped Gd2(MoO4)3 phosphors were prepared by using MoO3, Gd2O3 and Tb4O7 as starting materials via a solid state reaction with flux of NH4HF2. The X-ray diffraction was used to characterize the crystal structure of the final resultants. It was found that the products exist in orthorhombic phase with space group Pba2. Excitation and emission spectra indicated that the studied phosphors can absorb 200~300 nm lights, which corresponding to both the f-d and Mo-O transitions, and emit blue broad band and green narrow lines originate from MoO2-4 and f-f transitions, respectively. Meanwhile, the concentration quenching and fluorescence decays were also studied, and it was found that in the case of taking carbon powder as reductant, Tb4O7 can not be well reduced. The color coordinates for the phosphors various with Tb3+ concentrations, and that the color purity for the phosphors are not good. From the obtained results, it can be concluded that this phosphor is not a promising one for the practical applications.
