合成出了担载稀土有机配合物的无机-有机杂化中孔发光材料(Phen)2Eu/MCM-41，用X射线衍射、红外光谱、荧光光谱和紫外-可见漫反射光谱对所得样品进行了表征，并与相应的纯稀土配合物进行了比较．结果表明，所得杂化材料具有典型的中孔材料MCM-41的结构，且经组装后孔结构保持不变，在紫外光照射下，发出稀土离子的特征谱线，但与纯稀土配合物相比，其激发光谱发生蓝移，稀土Eu3+所处的格位对称性降低，荧光寿命延长．另外，对光谱性质进行了讨论．

A novel hybrid inorganic-organic mesoporous luminescent material (phen)2Eu/MCM-41has been synthesized and characterized by XRD, IR, fluorescence and diffuse reflection spectra. Incomparison with MCM-41, the hybrid mesoporous material has typical structure of MCM-41 andretains the same pore structure as MCM-41 after the assembly process. The hybrid mesoporousmaterial shows characteristic emission spectra of Eu3+ under UV irradiation, but the excitationspectrum has shifted to blue region compared to that of pure rare earth complex. The decrease of sitesymmetry of Eu3+ has been found. The fluorescence lifetime of (phen)2Eu/MCM-41 is longer thanthat of pure rare earth complex. The spectra of hybrid mesoporous material have been discussed.
