摘要：

Nanocomposite films of gold nanoparticles and TiO2 gel have been successfully prepared by combination of a surface sol-gel technique and layer-by-layer assembly. Thanks to surface hydroxyl groups of gold nanoperticles, gold particles were deposited as close-packed monolayers on TiO2 Gel Layers on TiO2 gel layers. The resulting nanocomposite contained ca. 50 wt % of gold. Multilayer films were successfully prepared by alternate assembly of TiO2 gel and gold nanoparticles.
