Аннотация
Samples of titanium dioxide, TiO2, doped with vanadium ions (0.1 ≤ [Vn+]0 ≤ 5.0 at. %) at high temperature, were prepared in a polycrystalline state and investigated using X-, Q-, and W-band electron paramagnetic resonance, EPR, spectroscopy. Substitutional and interstitial V4+ centers in TiO2 lattice have been both observed in EPR spectra, and their spin-Hamiltonian parameters were calculated. Portions of paramagnetic and diamagnetic species of Vn+ ions were estimated. The effect of additional high temperature annealing on the valence state of vanadium centers is discussed.
