| Abstract | ||||
| A glass system 45B2O3-50 Bi2O3-5MoO3 glass system containing various proportions of Dy2O3 was prepared by the conventional melt quenching technique. The density (ρ) and molar volume of the prepared glass is determined. The areas of BO3 and BO4 were obtained from the FTIR spectra deconvolution. The optical absorption and emission spectra have been systematically studied and discussed. Also using Judd-Ofelt parameters to study the local structure around Dy ions. The yellow to blue intensity ratio, (Commission Internationale de l'éclairage) CIE chromaticity diagram coordinates, and color temperature values correlated were also calculated using emission spectra to evaluate the emitted light. The results obtained indicate the usefulness of glass samples for potential white LED applications. | ||||
