Abstract:
The composite material of DCM-MSS with optical property has been successfully prepared by doping mesoporous silica spheres (MSS) with laser dye 4-dicyanomethylene-2-methyl-6-p-dimethyl-aminostyryl-4H-pyran (DCM) a self-assembly method. The investigations of optical microscope, XRD, FTIR, N2 adsorption-desorption, UV-Vis and PL characterization confirm that the dye molecules are mono-disperse in the channels of MSS in terms of a blue-shift of UV-Vis absorption peak. Red-shift of 100 nm in the PL emission peak was observed for the composite material compared with the dyes in solid. In addition, the transparent DCM-MSS with an average diameter of 800 nm showed the strong photoluminescence properties.
