Abstract
EPR and optical absorption investigations are carried out at room temperature on copper-doped MB4O7 (M = Zn, Cd)
glasses. The results indicate that the copper ions (Cu2+) enter the glass matrix into a tetragonally elongated octahedral site.
Crystal field and spin-Hamiltonian parameters are evaluated. The bonding parameters suggest that bonding between the
metal ion and ligands is partially covalent.
