Abstract
Nanocomposite films of gold nanoparticles and TiO2 gel have been successful ly prepared by combination of a surface sol-gel technique and layer-by-laye r assembly. Thanks to surface hydroxyl groups of gold nanoperticles, gold p articles were deposited as close-packed monolayers on TiO2 Gel Layers on Ti O2 gel layers. The resulting nanocomposite contained ca. 50 wt % of gold. M ultilayer films were successfully prepared by alternate assembly of TiO2 ge l and gold nanoparticles.
