Fabrication of Ultrathin Titanium Dioxide Films

Open Laboratory for Colloid and Interface Chemistry of State Educational Commission, Shandong University, Ji'nan 250100

Received Date: 18 April 1997
Revised Date: 23 September 1997

Excellent quality ultrathin TiO₂ films were obtained from tetrabutyl titanate and arachidic acid by a two-dimensional sol-gel process, followed with thermal decomposition of the complex multilayer Langnuirblodgett films. The UV-vis spectra of the multilayer films showed a blue shift of the absorption band relative to those of bulk TiO₂, inlplying the for-mation of nanoparticles of TiO₂-based condensates. Their uniformity and rutile type struc-ture were revealed by TEM and XRD results.
