Elemental composition of the nanoclusters was studied by X-ray photoelectron spectroscopy, their crystal structure was determined by X-ray diffraction, and their optical properties were characterized by UV-vis spectroscopy. Both as-prepared (without any additional postdeposition treatment) and annealed (in air at 420°C for 1 h) films were studied. Titanium nanocluster films were found to oxidize immediately when exposed to ambient atmosphere. The as-prepared nanoclusters were composed of both Ti and TiO2. The transformation from a metal to an oxide structure of the nanoclusters upon annealing ends up in a semistable anatase crystal form of TiO2 with traces of a thermodynamically stable rutile crystal form.
