摘要
A simple process were applied to the preparation of transparent meso-structure silica film which doped with laser dye at room temperatrue by solvent evaporation method. The SAXRD pattern of the film doped with Cou 151 indicates that the film retain mesopores structures. In the composite, the dye molecules were mono-disperse in the channels of meso-structure silica which was determined by blue shift in UV spectra. Red-shift in the PL spectrum was observed for the composite film compared with that of dye/CHCl3 solution and this strong fluorescence can take an important action in state dye laser and in optical sensors.
