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.
