Abstract

Zinc Aluminum Lithium borate (ZALB) glasses of different compositions doped with Cu2+ ions have been prepared using conventional melt quenching technique. X-Ray diffraction Electron paramagnetic resonance and Fourier transform infrared studies have been carried out for ZALB glasses. The XRD pattern of ZALB glass confirms the amorphous structure of the glass matrix. From EPR spectra in Cu2+ doped zinc aluminium lithium borate glass system, 〖 g〗_∥>g_⊥, showing the position of the Cu2+ ion in the glasses with tetragonally elongated octahedral (D4h) site. FTIR spectra showed that the increment of copper oxide caused the breaking of B-O-B bonds and by creating new and more bonds. FTIR findings likewise confirmed both the EPR and the findings of optical absorption, which suggested the major role of copper oxide in the formation of cross-linking bands.
