Abstract:

In this paper,laser dye molecules,such as Coumarin 151 molecules,were doped into mesoporous MCM-41 powders and fibers using crystallization inclusion method. The composites were characterized by Leica microscope,SAXRD,UV-Vis diffuse reflection spectrum. The fibers which doped with Coumarin 151 were 20 μm in width and 3\_5 mm in length. Both the powder and the fibers doped with Coumarine 151 were blue-shift in UV-Vis spectrum compared with the dyes in solid. Both the composites have luminescent properties.
