Abstract
The present manuscript deals with the preparation and structural studies of BaF2–TeO2 – Li2B4O7–CuO glasses. The glasses were made using the melt quenching procedure, and their properties were examined utilizing the density, absorption, FTIR, Raman, and EPR spectra. The lack of strong peaks in the XRD spectra provides evidence that the phase is non-crystalline. The samples' densities went up but their molar volumes went down. The transition between 2B1g and 2B2g is responsible for a broad absorption band in optical absorption spectra. With BaF2, the band gap values obtained from the Tauc plot were raised. The density and optical data were used to determine a number of additional characteristics. The existence of various structural groups in the glass structure was shown by the FTIR and Raman spectra. Calculated from EPR spectra, the spin- Hamiltonian and bonding parameter values explained the ligand field around the Cu2+ ions.
