采用高温固相法制得 Eu3+掺杂的 Lu2MoO6荧光粉，通过 X 射线衍射(XRD)及激发、发射光谱和衰减寿命等手段对样品的结构和发光性质进行了表征。XRD 结果表明：制备的荧光粉均为单斜结构。实验结果表明该样品在可见光谱范围内能够被近紫外光有效地吸收，该吸收来自 Mo6+–O2?吸收带。在掺杂10% Eu3+的情况下，发光最强。详细地研究最佳临界距离 Rc 和能量机制。Lu2MoO6：Eu3+红色荧光粉是一种可应用于近紫外激发白光 LED用的新型红色荧光粉。
The Eu3+ activated Lu2MoO6 phosphors were synthesized by high-temperature solid-state reaction method. The X-ray diffraction (XRD), excitation spectra, emission spectra and decay lifetime of the phosphors were measured to characterize the structure and luminescent properties. The XRD results show that all the prepared phosphors can be assigned to the monoclinic structure. The experimental results indicate efficient absorption of near ultraviolet light from the Mo6+?O2? group followed by intensive emission in the visible spectral range. The optimal content of Eu3+ is 10% (mole fraction). The critical distance Rc and energy transfer mechanism were also discussed in detail. This red emitting material may be applied as a promising red phosphor for the near ultraviolet excited white light emitting diodes.
