Abstract
In this work, the photoluminescence properties of bismuth borate glass doped with Dy3+ have been studied. Glasses were prepared using the glass composition formula 30Bi2O3 : (70-x)B2O3 : xDy2O3, where x is 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol%. Glass samples were fabricated by the use of the normal melt-quenching technique at the melting temperature of 1,100 °C at 3 hour time intervals. Glass samples were annealed at the temperature of 500 °C at 3 hour time intervals to remove thermal strain. From photoluminescence study, the emission spectra (excited at 451 nm) were observed three emission peaks, which are assigned to 4F9/26H15/2 (484 nm), 4F9/26H13/2 (574 nm), and 4F9/26H11/2 (661 nm) transitions, respectively. The luminescence intensities of all glasses are comparable and the strongest intensity peak at 574 nm was obtained.
