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.

关键词: 介孔SBA-15, 染料, 棒状, 单块, 薄膜

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.
