Samarium nanoparticle-doped silver oxide-incorporated zinc tellurite glass system: Structural, elastic, and Judd-Offelt intensity parameters

Abstract

The composition of the glass system of zinc tellurite [{(TeO2)0.7 (ZnO)0.3}0.99 (Sm2O3 NPs)0.01]1-y (Ag2O) y, with y = 0.005.0.01, 0.015, 0.02 and 0.025 mol fractions are fabricated using the traditional melt quenching method. The density of glass samples was calculated using the Archimedes principle with distilled water as an immersing liquid and the measurements have repeated a minimum of ten times to attain density with minimum error. It has been noted that as doping is increased, the density of the glass system falls but the molar volume increases. The XRD analysis of synthetic samples showed that the glasses are amorphous. At room temperature, the longitudinal and shear velocities of glass samples are determined using a 5 MHz frequency. To examine the quantitative study of the structure of synthesized glasses, the Poisson ratio (σ), elastic moduli, Debye temperature (θD) and softening temperature (TS) are computed and in-depth descriptions are given. The obtained data showed that silver oxide influences the host material by enhancing its properties and solidifying the glass network. Sm2O3NPs with a 72.43 nm particle size were discovered using high-resolution electron microscopy transmission (HR-TEM).The Judd-Offelt parameters (Ω2 = 4.94, Ω4 = 4.38 and Ω6 = 3.38) and the least-square fitting produced showed that the samples are appropriate candidates for laser. The main goals of this study are to analyze the compositional dependency of the elastic properties of produced glass systems using the Judd-Offelt analysis and to ascertain the impact of samarium oxide concentration on the elastic properties of zinc tellurite glass systems.
