Abstract
Abstract Li2O-BaO-B2O3: Cr2O3 glass samples were prepared by adapting the Melt-quenching method. The pre prepared glass samples were characterized by the XRD and confirm the amorphous nature of the samples. Various physical parameters were estimated employing experimental densities and refractive index. The bands observed in the Optical absorption spectra were assigned and described based on the electronic transitions by using the TS diagrams. Crystal field (Dq) and Racah parameters (B and C) were calculated by the crystal field relations. Direct and Indirect optical band gaps were evaluated using Davis and Mott relation from the absorption edges. Correlate these results with Infrared and ESR studies. Finally, discussed the structural behavior of the Chromium ions in Li2O-BaO-B2O3glass samples was analyzed.
