Analysis of UV-Vis absorption spectrum for the evaluation of structural chemistry of LAST glass containing Fe3+ ions

Structural chemistry of Fe3+ doped LAST glass has been analyzed using the UV-Vis absorptionspectra. Optical parameters like absorption and extinction coefficients, direct and indirect opticalband gaps, Fermi energy level as same as Urbach energy of samples were calculated using theirabsorption spectra. It was revealed that Fe3+ ions have network forming role in the glass structureby increasing the Bridging Oxygen’s (BOs) in the matrix.
