采用高温固相反应法制备了Lu2MoO6: 3% Eu3+与x% Li+共掺杂（x= 0 ~ 40 mol）荧光粉。研究了这些荧光粉的结构和发光性能。x射线衍射（XRD）结果表明，所制备的荧光粉均可分配到单斜相，且与Li+离子共掺杂未改变其晶体结构。激发光谱和发射光谱表明，样品在365 nm处可以有效地被近紫外光激发，并在610 nm处表现出强烈的红色发射。实验结果表明，与Li+离子共掺杂后，Lu2MoO6:Eu3+荧光粉的红色发光强度大大增强。发光强度的增强可能是Eu3+离子周围局部场对称性的改变、晶化的改善和Li+离子诱导晶粒尺寸增大的结果。
Lu2MoO6: 3% Eu3+co-doped with x% Li+(x= 0–40 mol) phosphors were synthesized by high-temperature solid-state reaction method. The structure and luminescent properties of these phosphors were investigated. The X-ray diffraction (XRD) results show that all prepared phosphors can be assigned to monoclinic phase and codoping with Li+ions does not change their crystallographic structure. The excitation and emission spectra show that the samples can be effectively excited by the near ultraviolet light at 365 nm and exhibit strong red emission centered at 610 nm. The experimental results indicate the red luminescent intensity of Lu2MoO6:Eu3+phosphors has been greatly enhanced by codoping with Li+ions. The enhancement of the luminescent intensity can be the consequence of the modification of the local field symmetry around the Eu3+ion, improved crystallization, and the enlarged grain size induced by the Li+ions.
