Abstract :
In this study, zinc aluminum lithium borate (ZALB) glasses of different compositions doped with Cu2+ ions were prepared using conventional melt quenching technique. X-Ray diffraction (XRD), electron paramagnetic resonance (EPR), and Fourier transform infrared
(FT-IR) studies were carried out for ZALB glasses. The XRD pattern of the ZALB glass confirmed the amorphous structure of the glass
matrix. The EPR spectra of the Cu2+ doped zinc aluminium lithium borate glass system, g > g, etermined the position of the Cu2+ ion in the glasses at the tetragonally elongated octahedral (D4h) site. FT-IR spectra showed that the increment of copper oxide led to the cleavage
of B-O-B bonds and formation of more new bonds. In addition, FT-IR findings also confirmed the both EPR results and the findings from the optical absorption. Our results highlight the major role of copper oxide in the formation of cross-linking bands.
