The effects of ionic liquid amount, synthesis time and temperature were investigated. The structure and characteristics of molecular sieve samples were characterized by X-ray diffraction(XRD),scanning electron microscopy (SEM), thermo gravimetric analysis(TGA). The results indicate that AlPO-11 molecular sieve could be synthesized by 1-ethyl-3-methylimidazolium bromide ([Emim]Br) ionic liquid as both the solvent and template.展开更多

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.展开更多
