STUDY OF ELECTRON PARAMAGNETIC RESONANCE SPECTRA OF LEAD BOROVANDATE GLASSES CONTAINING MoO3 CONTENT

The oxide glasses MoO3-PbO-B2O3:V2O5 have been investigated by the standard melt-quenching technique. The amorphous nature of studied glasses is ascertained by X- ray diffraction patterns. Electron paramagnetic resonance (EPR) of these glasses has been studied. The hyperfine coupling parameter (P) decreases with an increase in MoO3 content. The increase in the value of the Fermi contact interaction term (K) with an increase in MoO3 content is due to an increase in the tetragonality of the V4+O6 complex.
