摘　　要：采用水热-组装法、溶剂挥发法等材料合成方法制备了不同形貌(粉末棒状、单块、薄膜)负载染料的介孔SBA-15复合材料,并开展光学性质研究.通过TEM,XRD,N2吸附-脱附表征证明所合成的各种形貌SBA-15材料均具有规则有序介孔结构,组装染料后复合材料的形貌及结构保持完整;Uv-vis,PL表征表明染料在SBA-15孔道中呈单分散状态,负载染料后的复合材料具有发光特性.Dyes have been grafted into the channels of mesoporous SBA-15 materials with different morphologies（rod-like powders,monolith and film）,which were synthesized by hydrothermal and evaporate-solvent methods,respectively.The investigations of TEM（transmission electron microscopy）,XRD and N2 adsorption-desorption confirmed that the different composite materials all remaining their ordered meso-structures after dye loading.Uv-vis and PL investigations show that the dye molecules are mono-dispersing in the channels of different dye containing composite materials.All the characterizations indicate that the composite materials have the potential to be used in optical sensors or solid-state dye laser.
