title: Tunable Nanostructures and Crystal Structures in Titanium Oxide Films.
abstract: Controllable nanostructures in spin coated titanium oxide (TiO(2)) films have been achieved by a very simple means, through change of post deposition annealing temperature. Electron beam imaging and reciprocal space analysis revealed as-deposited TiO(2) films to be characterized by a dominant anatase phase which converts to the rutile form at 600 degrees C and reverts to the anatase modification at 1,200 degrees C. The phase changes are also accompanied by changes in the film microstructure: from regular nanoparticles (as-deposited) to nanowires (600 degrees C) and finally to dendrite like shapes at 1,200 degrees C. Photoluminescence studies, Raman spectral results, and X-ray diffraction data also furnish evidence in support of the observed solid state phase transformations in TiO(2).
