    The paper is focused on a study of formation of TiOxNy thin films prepared by pulsed magnetron sputtering of metallic Ti target. The films were deposited by high-power impulse magnetron sputtering working with discharge repetition frequency f = 250 Hz at low (p = 0.75 Pa) and high (p = 10 Pa) pressure. Post-deposition thermal annealing was not employed. The chemical composition from x-ray photoelectron spectroscopy diagnostic reveals formation of TiOxNy structure at low flow rate of oxygen in the discharge gas mixture. This result is confirmed by XRD investigation of N element's incorporation into the TiO lattice. Decrease in band-gap to values Eg ~ 1.6 eV in TiOxNy thin film is attributed to formed TiN bonds. The discharge properties were investigated by time-resolved optical emission spectroscopy. Time evolution of particular spectral lines (Ar+, Ti+, Ti) is presented together with peak discharge current.
