Abstract

42%P2O5- 40%ZnO- 2%CaO- (16-x) %Na2O-xCu2O glass system (x=o, 2, 4, 6, 8, 10%mol) were prepared by conventional melt-quenching technique. It was investigated by means of electron paramagnetic resonance (EPR) to study the structural changes induced by different amount of copper ions. The spin Hamiltonian parameters like g∥, g⊥ and A∥ show that Cu+2ionare in tetrahedral coordination with dxy as the ground state. Modification of EPR band width by increasing copper content suggests that band consists of two overlapping bands; one of them is related to asymmetric band due to isolated copper ions and the other is symmetric due to cluster ions Cu+2-Cu+2. Calculation of the optical basicity indicates to that polarizability decrease by increasing copper content due to increase electron cloud density at the Cu2+ site.
