Abstract

In this investigation, we reported three glass samples of Nd (III) ions doped boro-tellurite-germanite glasses. The chemical composition of (35-x) BO–20TeO-10GeO-35MgO-xNdO where x = 2.5, 5, and 7.5, all in mol%, was used to synthesize an optical glass. XRD, FTIR, and optical absorption were utilized to evaluate the structural and optical properties of Nd2.5, Nd5.0, and Nd7.5. X-ray diffraction was measured in the spectra range of 10–80°. Additionally, spectra of FT-IR in the wavenumber range of 400–4000 cm were reported to investigate all structural groups. Several absorption peaks related to the transitions from ground level I to the other excited state were investigated. Various mechanical, optical, and physical properties were calculated theoretically and analyzed to determine the role of the rare earth ions (Nd). The optical electronegativity (χ) and optical basicity (Λ) results showed a reduction in the strength of the bond and formed an ionic bond in the glass structure due to adding NdO. These results align with the reduction in the elastic modulus results by adding NdO instead of BO. Radiation shielding parameters like HVL, TVL, MFP, and Z were thoroughly reported for all Nd2.5, Nd5.0, and Nd7.5, which showed slight improvement when NdO was added instead of BO.

钕 (III) 离子对 B2O3-TeO2-GeO2-MgO 玻璃成分在光学和电离防护应用中的作用

在这项研究中，我们报告了三种掺杂钕 (III) 离子的硼碲锗石玻璃样品。我们采用 (35-x) BO-20TeO-10GeO-35MgO-xNdO 的化学成分合成了一种光学玻璃，其中 x = 2.5、5 和 7.5，均为 mol%。利用 X 射线衍射、傅立叶变换红外光谱和光学吸收来评估 Nd2.5、Nd5.0 和 Nd7.5 的结构和光学特性。X 射线衍射的光谱范围为 10-80°。此外，还报告了波长范围为 400-4000 厘米的傅立叶变换红外光谱，以研究所有结构基团。研究了与从基态 I 到其他激发态跃迁有关的几个吸收峰。对各种机械、光学和物理特性进行了理论计算和分析，以确定稀土离子（钕）的作用。光学电负性（χ）和光学碱性（Λ）结果表明，加入氧化钕后，玻璃结构中的键强度降低，形成了离子键。这些结果与添加氧化钕而不是氧化银后弹性模量降低的结果一致。对所有 Nd2.5、Nd5.0 和 Nd7.5 的辐射屏蔽参数（如 HVL、TVL、MFP 和 Z）进行了详细报告，结果表明，添加 NdO 而不是 BO 后，辐射屏蔽参数略有改善。
