| Abstract | Sodium barium bismuth borate glass samples (NaBaBiB) doped with various concentrations of Dy3+ ions were produced usingthe conventional melt quenching technique at 1,100 C for 3 hours. The physical, optical and luminescence properties of theNaBaBiB glasses that were produced investigated. The results showed that the density and refractive index of the glass samplesincreased with increasing Dy2O3 concentration. The optical absorption spectra of glasses were measured in the wavelength of200 1,800 nm. The intensity of all of the absorption bands increased with increasing concentrations of Dy2O3 in the sample.The luminescence properties of Dy3+ doped NaBaBiB glasses were investigated. The emission spectra for glasses showed peaksat 483, 576 nm and 665 nm. These corresponds to the 4F9=2 ! 6H15=2, 6H13=2 and 6H11=2 transitions under 453 nm excitation.The optimal concentration of Dy2O3 in NaBaBiB glasses was found to be 1.5 mol%. |
