Abstract

Zinc boro-phosphate glasses doped with Dy3+ ions (DZBP) have been synthesized following the melt quenching technique and their spectroscopic properties were studied through absorption and emission spectra. The bonding parameters (δ and β) and Judd-Ofelt (JO) intensity parameters were calculated from the absorption spectra. The luminescence properties of the present Dy3+ doped glasses have been analyzed through radiative properties. The luminescence spectra of the Dy3+ doped zinc boro-phosphate glasses exhibit two intense emission bands corresponding to the 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions. The Y/B intensity ratio values have been calculated from the emission spectra of the prepared glasses and the combination of dominant blue and yellow emissions generate white light emission. The results obtained from the CIE chromaticity diagram suggest that the present Dy3+ doped glasses are suitable for white light applications.
