Physical, optical and structural characterizations of Dy3+-doped lead borate glasses

In the current studies optical, physical and structural properties of rare-earth doped borate glasses have been reported. Bulk samples were prepared by using melt quenching technique with nominal composition 70B₂O₃-(17-x)ZnO-10PbF₂-3Na₂O-xDyF₃ and 60B₂O₃-(27-x)ZnO-10PbF₂-3Na₂O-xDyF₃, where (x=0,1). XRD analysis was used to confirm the amorphous nature of prepared samples. Optical and structural properties of as prepared samples were studied using UV-Visible and FTIR absorption spectra. The undoped and doped glasses exhibit characteristic absorption bands due to the presence of rare earth ion. A decrease in the band gap has been observed with the addition of rare earth ion. Variations in density have been observed with the addition of rare earth ion.
