摘　　要：通过结晶包覆的方法将激光染料香豆素151成功地负载到具有介孔结构的MCM-41粉体和纤维中,制备了具有光致发光特性的MCM41粉体和纤维材料,并通过SEM,SAXRD,UVVis和PL进行了表征.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 blueshift in UV-Vis spectrum compared with the dyes in solid. Both the composites have luminescent properties.
