Abstract

Various methods have been used to study the physical properties of the V2O5-Fe2O3 and V2O5-Fe2O3-Li2O systems, including X-ray, electron microscope, Mössbauer effect, NMR and thermogravimetric measurements. The iron ions are approximately equally distributed in substitutional and interstitial sites in the V2O5 lattice. The maximum number of iron ions dissolved in the V2O5 matrix corresponds to 4 mol % Fe2O3. In all the samples a quantity of Fe2O3 which has not been included in lattice is observed. The V2O5-Fe2O3 and V2O5-Fe2O3-Li2O systems are formed from solid solutions mixed with very small Fe2O3 particles. The analysis of the charge compensation of iron ions suggests that V2O5 is a quasi-amorphous semiconductor. Irradiation of V2O5-based samples with an electron beam induces the V2O5 platelets to convert to the VO x phase.
