AbstractIn the present study, the optical characterization of borate glasses with composition 35Li2O − 10ZnO − 55B2O3 − xMnO2: x = 0, 0.5, 1.0, 1.5, and 2.0 wt% has been investigated. The absorption spectra measurements within the wavelength domain 200–1000 nm have been carried out. The optical energy gap of the investigated samples using the absorption spectrum fitting (ASF) model has been calculated. The molar […]
