Structural and Optical Investigation of Rare Earth Doped Oxyfluoride Glasses

Abstract

UV-Vis and FTIR analyses have been performed on an aluminosilcate base glass doped with two different rare earths (Dy3+ and Eu3+) with varying concentrations. The glasses were prepared by conventional melt quenching technique. While the absorption intensity of the observed bands was found to increase with increase of RE concentration, the RE doping did not cause any new structural unit and the FTIR spectra practically remained unchanged.
