摘　　要：[Ru (bpy)_3]^(2+)/MCM-41 composite material obtained by loading tris(2, 2' - bipyridine)ruthenium(Ⅱ) ([Ru (bpy)_3]^(2+) ) in siliceous mesoporous MCM-41 was characterized by X-ray powder diffraction, UV-Vis absorption and emission spectroscopies. The absorption spectrum of [Ru(bpy)_3]^(2+) /MCM-41 is similar to that of [Ru (bpy)_3]^(2+) aqueous solution, whereas its emission spectrum exhibits hypsochromic shift compared to the solution spectrum. On the other hand, the peak position of the emission spectrum of [Ru(bpy)_3]^(2+)/MCM-41 shifts towards longer wavelength when the loading amount increases.[Ru (bpy)_3]^(2+)/MCM-41 composite material obtained by loading tris(2, 2' - bipyridine)ruthenium(Ⅱ) ([Ru (bpy)_3]^(2+) ) in siliceous mesoporous MCM-41 was characterized by X-ray powder diffraction, UV-Vis absorption and emission spectroscopies.
