✦ Synopsis

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 anisotropic hyperfine structure. The spin-Hamiltonian parameters and or-bonding parameter, ~2 are calculated. Varying the fluoride ion concentration and its effect on these parameters is also discussed.

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 conc
