Cu super(2+) containing TeO sub(2)-B sub(2)O sub(3)-PbO glasses studied by EPR

EPR absorption spectra of Cu super(2+) were investigated in vitreous matrices of the system [70TeO sub(2)-25B sub(2)O sub(3)-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 s...

Zusammenfassung:EPR absorption spectra of Cu super(2+) were investigated in vitreous matrices of the system [70TeO sub(2)-25B sub(2)O sub(3)-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 super(2+) environment. The concentration of the paramagnetic species that cause the EPR absorptions decreases considerably at the upper limit of the investigated compositional range.
