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 DyO, YO co-activated telluro-borate glass developed using the melt-quenching method. The glassy quality and the elements component of the specimens were observed using XRD and EDX analyses. The addition of YO rise the glass density from 2.956 to 3.303 g/cm the refractive index from 2.5 to 2.7. These changes are due to the increase in polarizability and non-bridging oxygen (NBO). The photoluminescence (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 convolution of Bi ions transitions corresponding to the non-centrosymmetric site respectively, the weak emission bands are due to F → H and F → H Dy transitions. Hence, the low symmetrical features of both Bi and Dy ions were confirmed. The increase in the Vickers hardness of the glass from 536.7 to 1366.9 indicates the influence of YO addition on the mechanical 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 photonic, and laser optics.
玻璃基材料在广泛科学领域的成功应用取决于其相关的物理、光学、热学和力学性能。本文研究了采用熔体淬火法制备的DyO、YO共激活碲硼酸盐玻璃的结构、物理、热学、光学和力学性能。使用XRD和EDX分析观察了试样的玻璃质量和元素组成。添加YO使玻璃密度从2.956 g/cm³提高到3.303 g/cm³，折射率从2.5提高到2.7。这些变化是由于极化率和非桥氧（NBO）的增加。光致发光（PL）光谱显示在550 nm处有一个宽峰，在573和664 nm处分别有额外的弱发射峰。虽然观察到的较宽峰可分别与对应于非中心对称位点的Bi离子跃迁的卷积相关，但弱发射带是由于F→H和F→H Dy跃迁。因此，证实了Bi和Dy离子的低对称特征。玻璃的维氏硬度从536.7增加到1366.9表明添加YO对玻璃力学性能的影响。这些发现有助于增进我们对玻璃成分行为及其在光子学和激光光学等学科中潜在应用的理解。
