Synthesis and growth of uniform titanium dioxide nanowires

Titanium thin films were evaporated on glass substrates by electron beam evaporation of a pure Ti target.The Ti films were then annealed at different temperatures (350 °C and 500 °C) in a conventional tube furnace underflowing oxygen gas for one hour each. It was found that with the annealing temperature of 500 °C and rate of oxygenflow of 40 sccm a uniform distribution of TiO2 nanowires grow on the films. The resultant nanowires have finediameter with very narrow distribution in size. The effect of annealing temperatures on the structure, optical properties,and morphologies were presented and discussed applying X-ray diffraction, optical absorption and transparencyspectrum and field emission-scanning electron microscope.
