Abstract

Dysprosium doped barium bismuth borate glasses (BBOD) with the chemical composition (75-x) H3BO3+ 15BaCO3+ 10 Bi2O3 + x Dy2O3 (where x= 0.05, 0.1, 0.25in wt %) were prepared by melt quenching method. XRD analysis was used to confirm the amorphous nature. The prepared glass sample was characterised through optical absorption and fluorescence spectra. The presence of stretching and bending vibrational modes of borates (BO3, BO4 and non-bridging oxygen atoms) in the prepared glasses were explored through FTIR analysis. Thermal analysis reveals the homogenous formation of the glasses. The glass transition temperatures were also obtained from the DSC spectra. Photoluminescence spectra of the prepared glasses reveal two intense emission bands in the visible regions (blue and yellow). The x, y color chromaticity coordinates of the prepared glasses were analysed using a CIE 1931 color chromaticity diagramand it is presented..
