AB  - Thin films of titanium oxides, titanium oxynitrides and titanium nitrides were deposited on glass substrates by the methods of direct current (DC) and pulsed magnetron sputtering and cathodic arc evaporation. Phase analysis of the deposited films by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) showed the presence of phases with various Ti oxidative states, which indicated a high concentration of oxygen vacancies. The films morphology was investigated by scanning electron microscopy (SEM). Investigations of the films wettability, either with water or ethylene glycol, showed that it depends directly on the concentration of oxygen vacancies. The wettability mechanism was particularly discussed.

AB  - Optical properties of TixOy thin film, of thickness 125 nm, obtained by pulsed magnetron sputtering were investigated in this paper. XRD analysis revealed the presence of anatase, rutile, TiO, Ti2O3and Ti3O5phases. XPS analysis showed similar results. SEM analysis showed quite smooth surface of the film. Spectroscopic ellipsometry revealed sharp decrease of refractive index in wavelength range 300-500 nm and extremely low values of extinction coefficients which are less than 0.01 at wavelengths equal to or higher than 500 nm.

AB  - Structural and optical properties of nanometric titanium oxide (TixOy) films obtained by cathodic arc plasma deposition were investigated. Phase analysis by x-ray diffraction and Fourier-transform infrared spectroscopy showed the presence of anatase, rutile, Ti2O3, Ti4O7 and amorphous phases. Scanning electron microscopy images showed well-developed surface morphology with nano-patterns. Spectroscopic ellipsometry revealed film thicknesses of 53 and 50 nm, variable refractive indices dependent on the light wavelength and close to zero extinction coefficients for wavelengths higher than 500 nm. On the basis of ultraviolet-visible spectroscopy data and using the Tauc equation, band gap values for direct and indirect electron transitions were determined.

AB  - Metamaterials based on TixOy with ultra-high and near-zero refractive indices were obtained by DC magnetron sputtering. The data on refractive indices, extinction coefficients, film thickness, and band gaps, obtained by spectroscopic ellipsometry, showed very high potential of these materials as metamaterials. Phase analysis performed by XRD revealed the presence of titanium phases with lower titanium oxidation states resulting from high concentration of oxygen vacancies, which are crucial for such extraordinary jumps and drops of refractive indices. Numerous band gaps for direct and indirect electron transitions additionally confirmed unique properties of these materials.
