Abstract: V4+ ESR studies were carried out in the system of sodium boro-vanadate glasses (Na2O-B2O3-V2O5), and V4+ ESR spectra were measured and analysed. It was found that V4+ ions present in the glasses were in the form of vanadyl-type ions VO2+. The structure of the V4+ ions was an octahedral six co-ordination with a tetragonal compression. The bonding properties of V4+ ions were discussed as well.
