中文摘要organic-inorganic hybrid sio2 xerogels were prepared by the sol-gel method under various preparation conditions and compositions by using tetraethoxysilane (teos), (3-aminopropyl) triethoxysilane (a-ps), (3-glycidoxypropyl) trimethoxysilane (gps), organic acid (ch3cooh) and inorganic acids (hcl, hno3, h2so4) as the main precursors. luminescence and ft-ir spectra were used to characterize the resulted hybrid sio2 xerogels. the result of ft-ir spectrum shows that the xerogels are composed of non-crystalline -si-o-si- networks containing some organic groups such as -nh, -ch and -oh. under the excitation of 365 nm, all the hybrid xerogels exhibit strong luminescence in the blue region, but the emission intensity and position depend on the starting precursor compositions to a large extent. suitable amount of polyethylene glycol (peg500 and peg10000) in the hybrid xerogels can enhance the emission intensity. additionally, the emission intensity of the hybrid xerogels increases with heat treatment temperature in the range of ambient to 200degreesc, and vacuum condition is also able to enhance the emission intensity.
