Effect of yttrium on the physical, elastic, and structural properties of neodymium-doped lead borotellurite glass

In this study, a series of glass systems with a composition of (49 − x)H₃BO₃–35TeO₂–15PbO–1.0Nd₂O₃–xY₂O₃ (x = 0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 mol%) was prepared via melt-quench technique. The effect of Y₂O₃ content on the density, molar volume, oxygen packing density, elastic, and structural properties were investigated. The density and molar volume were found to vary concerning Y₂O₃ content. Ultrasonic non-destructive testing was employed at room temperature for measuring the elastic properties of the prepared glass samples. The density data, ultrasonic velocities, and measured elastic moduli were found to be composition dependent with Y₂O₃ content. The Y₂O₃ modifier was expected to change the physical properties of neodymium-doped lead borotellurite glasses. The structure analyzed using X-ray diffraction was confirmed the amorphous nature of the prepared glasses. Fourier Transform Infrared Spectroscopy has been carried out and reveals that the inclusion of Y₂O₃ into the glass system tends to increase the number of bridging oxygen atoms. All element study of the glass sample was proved by energy dispersive X-ray analysis.
