Abstract

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
