摘　　要：室温下制备出介孔材料MCM-41,将稀土离子铕和荧光染料曙红Y作为客体组装到MCM-41主体孔道中,制得Eosin Y/Eu-MCM-41复合型介孔材料组装体。采用XRD、RTIR、N2吸附和激发与发射光谱等技术对样品结构和性能进行了表征。结果表明,制备出的复合型介孔材料组装体仍保持MCM-41的六方有序结构,客体分子主要存在于主体介孔材料孔道中。激发与发射光谱显示曙红Y为发光中心,Eosin Y/Eu-MCM-41组装体的发光强度与Eosin Y-MCM-41比较呈规律性变化,当Eosin Y/Eu摩尔比为1∶1时其发光强度最强。Mesoporous material MCM-41 was prepared at room temperature, then rare earth ion Eu^3＋ and fluorescence dye Eosin Y were assembled in the channels of MCM-41. The samples were characterized by XRD,RTIR, Nitrogen adsorption, and fluorescence measurements. Results showned that Eosin Y/Eu-MCM-41 mesoporous assembly material possessed the mesoporous MCM-41 structure with ordered hexagonal arrangements, while Eu^3＋ and Eosin Y were assembled in the channels of host body. In addition, fluorescence spectrum showed that the luminescencet center was Eosin Y. The luminescent intensity of Eosin Y/Eu-MCM-41 was much stronger than that of Eosin Y- MCM-41, and as the mole ratio of Eosin Y/Eu was 1：1, the luminescent intensity reached the strongest value.
