EPR and optical absorption by Cu{sup 2+} ions in ZnO−Li{sub 2}O−Na{sub 2}O−K{sub 2}O−B{sub 2}O{sub 3} glasses
Abstract
Electron Paramagnetic Resonance (EPR) studies at room temperature in the x-band frequencies on xZnO−10Li{sub 2}O−10Na{sub 2}O−10K{sub 2}O−(69−x)B{sub 2}O{sub 3}−1CuO (x=0,2,4,6 and 8 mole%) glass systems were reported. The non-linear variation of spin-Hamiltonian parameters with ZnO content indicated the change in the ligand field strength around Cu{sup 2+} ions in the host glass. The ground state of Cu{sup 2+} ions in the glass is designated as d{sub x{sup 2}−y{sup 2}} orbital ({sup 2}B{sub 1g}) while the observed symmetry around it is tetragonally distorted octahedral. The molecular orbital coefficients α{sup 2}, β{sup 2} and β{sub 1}{sup 2} are evaluated for Cu{sup 2+} doped samples. The non-linear variation in the values of parameters indicated mixed alkali effect in the glasses.
