Structural, chemical and magnetic features of gold nanoshapes integrated-Er2O3-doped tellurite glass system prepared by a conventional melt-quenching technique
Rare earth ions-doped oxide glasses with improved traits are needed for sundry applications. Based on this fact, physiochemical and magnetic characteristics of Er3+ -doped lead–tellurite glasses embedded with gold nanoshapes (Au-NSPs) were customized via preparation and characterization.

| description | Rare earth ions-doped oxide glasses with improved traits are needed for sundry applications. Based on this fact, physiochemical and magnetic characteristics of Er3+ -doped lead–tellurite glasses embedded with gold nanoshapes (Au-NSPs) were customized via preparation and characterization. Glasses of composition 78.95TeO2–15PbO–5PbCl2–1Er2O3–0.05AuCl3 were made using conventional melt-quenching techniques at varying (1, 6, 16, and 24 h) heat treatment durations (HTDs) to optimize their morphology, structure, chemical, and magnetic properties. Structure analysis verified the amorphous nature of the as-quenched samples and the homogeneous distribution of Au-NSPs within a network matrix with an average diameter ranged from 1.32 to 7.12 nm. Significant chemical functional groups of the glasses were detected at 360 and 598 cm‒1, attributed to the number of non-bridging oxygen (NBO) in glass and the conversion of TeO4 tbp into TeO3 polyhedra through TeO3+1. The magnetic behavior of the glasses was due to the diffusion-limited growth of Au-NSPs as evidenced from the ESR and VSM results. Saturation magnetization and magnetic coercivity were in the range of 4.61 × 10–2 to 10.614 × 102 emu/g) and 1441.60 to 1992.20 Oe, respectively. The variations of g-factor, resonant magnetic field, and peak-to-peak line-width of the glasses were established to be promising for various functional applications especially for biomedical devices as antiviral screen protectors. |
