Abstract: Excellent quality ultrathin TiO2 films were obtained from tetrabutyl titanate andarachidic acid by a two-dimensional sol-gel process, followed with thermal decomposition ofthe complex multilayer Langnuirblodgett films.The UV-vis spectra of the multilayer filmsshowed 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.

Key words: ultrathin TiO2 film, fabrication, sol-gel method, LB technique
