Structural and elastic properties studies of yttrium lead borotellurite glass doped with neodymium oxide

The Nd3+ doped yttrium lead borotellurite glasses with the chemical composition (49- x)H3BO3-35TeO2-15PbO-1.0Y2O3-xNd2O3 (x = 0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 mol%) were successfully synthesised by using melt-quenching technique. The amorphous nature of all the glass samples were confirmed through the XRD spectra and various structural parameter were determined. The ultrasonic velocities and elastic moduli were measured from the measured density and ultrasonic velocities. From the analysis, it indicates that the physical properties of these glasses depend upon the role of Nd2O3 content inside the glass system and the compositional changes of the glass system.
