✦ Synopsis

EPR absorption spectra of Cu 2 + were investigated in vitreous matrices of the system [70TeO2-25B2Os-5PbO] over a wide range of concentrations. The detected absorptions are strongly dependent on the matrix composition. Fluctuations of the ligand field were evident in the Cu 2 § environment. The concentration of the paramagnetic species that cause the EPR absorptions decreases considerably at the upper limit of the investigated compositional range.

Electron paramagnetic resonance (EPR) studies have been performed on the glass system (30-x)NaF-xNa20-50B203-20Bi203 doped with CuO as a paramagnetic probe. The calculated gvalues indicate that Cu 2÷ is in a tetragonally elongated octahedral co-ordination, and the Jahn-Teller character gives rise to
