Exploring the properties of Dy2O3-Y2O3 Co-activated telluro-borate glass: Structural, physical, optical, thermal, and mechanical properties

The successful application of glass-based materials in a wide range of scientific fields depends on the associated physical, optical, thermal, and mechanical properties. This article investigate the structural, Physical, thermal, optical, and mechanical properties of Dy2O3, Y2O3 co-activated telluro-borate glass developed using the melt-quenching method. The glassy quality and the el-ements component of the specimens were observed using XRD and EDX analyses. The addition of Y2O3 rise the glass density from 2.956 to 3.303 g/cm3 the refractive index from 2.5 to 2.7. These changes are due to the increase in polarizability and non-bridging oxygen (NBO). The photo-luminescence (PL) spectra revealed a broad peak at 550 nm and additional weak emission peaks at 573 and 664 nm, respectively. While the observed broader peak can be linked to the convo-lution of Bi3+ ions transitions corresponding to the non-centrosymmetric site respectively, the weak emission bands are due to 4F9/2 & RARR; 6H13/2 and 4F9/2 & RARR; 6H11/2 Dy3+ transitions. Hence, the low symmetrical features of both Bi3+ and Dy3+ ions were confirmed. The increase in the Vickers hardness of the glass from 536.7 to 1366.9 indicates the influence of Y2O3 addition on the me-chanical properties of the glasses. The findings help to improve our understanding of the behaviour of the glass composition and its prospective applications in disciplines such as pho-tonic, and laser optics.

Automated summary

This article investigates the structural, physical, thermal, optical, and mechanical properties of telluro-borate glass co-activated with Dy2O3 and Y2O3. The addition of Y2O3 increases the glass density and refractive index, and affects the photo-luminescence spectra. Furthermore, the Vickers hardness of the glass is increased by the addition of Y2O3, indicating an improvement in mechanical properties. These findings enhance our understanding of the glass composition and its potential applications in fields such as photonics and laser optics.
