摘　　要：采用超声波辅助,将稀土配合物Eu(Phen)2Cl3装入中孔分子筛MCM-41孔道,合成了不同组装量的杂化材料Eu(Phen)2Cl3/MCM-41。运用XRD、N2吸附-脱附、FTIR、荧光光谱等手段对杂化材料进行了表征,研究表明稀土配合物已进入分子筛孔道,且随着配合物嵌入量的增加,杂化材料的荧光发射也逐渐增强。当Eu(Phen)2Cl3的组装量达到饱和(7.17%)时,其荧光强度最大。与纯配合物Eu(Phen)2Cl3相比,Eu(Phen)2Cl3/MCM-41的热稳定性提高了约100°C。A series of dopant concentrations hybrid materials of Eu （Phen） 2 Cl3/MCM-41 have been synthesized by tdtrasound technology. The characterization of XRD, N2-adsorption-desorption. FTIR and luminescence spectrum showed that the rare earth compound had doped into the holes of mesoporous material MCM-41. The luminescence intensities of the hybrid materials are improving with the increase of the rare-earth complexes dopant concentration. The hybrid material has the maximal luminescence intensity when it has the saturated dopant concentration （7. 17 % ）, Compared to the pure rare-earth complex, the thermal stability of the hybrid materials enhances by 100 ℃
