In this work, the multivalent transition metal oxide, Cu2O3, has been added in different content to the primary constituents of the Ca/Na lead Arseborate oxide glass. These required glasses were created using the fast-quenching method using the chemical formula: {50 wt% Na2B4O7.10 H2O–17 wt% CaO–17.5 wt% PbO–17.5 wt% As2O3} − x Cu2O3 where x = 0, 0.25, 0.5, 0.75, and 1g. Utilizing X-ray diffraction (XRD) patterns, electron spin resonance absorption (ESR), and Fourier transform infrared (FTIR) spectra, the interior structures of the prepared solids have been examined. Both XRD patterns and FTIR charts clarified that the amount of Cu2O3, in the range of 0–1g, did not affect the amorphous nature of Ca/Na lead-based Arseborate oxide glass, with the existence of four fundamental building units in each sample (BO3, BO4, PbO4, and AsO4). According to the optical characterization using UV–vis spectra, the increase in Cu2O3 concentration led to a decrease in optical energy gaps while increasing optical absorbance, optical reflectance, the plasmon frequency, calculated linear and nonlinear refractive indices, optical conductivity, and optoelectric conductivities. The results of the calculations and radioactive measurements indicated that the effective mass number increased as the amount of Cu2O3 content was increased, while the mean free path MFP and the half-value layer HVL decreased. According to the results, the examined glasses can be used as IR filters and shields.

低浓度Cu2O3添加剂对砷硼酸铅钙/钠玻璃结构内相、光学性能和辐射γ射线屏蔽能力的影响
在这项工作中,多价过渡金属氧化物Cu 2 O 3以不同的含量添加到Ca/Na铅砷硼酸盐氧化物玻璃的主要成分中。这些所需的玻璃是通过快速淬火方法使用化学式制造的:{50 wt% Na 2 B 4 O 7 .10 H 2 O–17 wt% CaO–17.5 wt% PbO–17.5 wt% As 2 O 3 } − x Cu 2 O 3其中x = 0、0.25、0.5、0.75 和1g。利用 X 射线衍射 (XRD) 图案、电子自旋共振吸收 (ESR) 和傅里叶变换红外 (FTIR) 光谱,检查了所制备固体的内部结构。XRD图谱和FTIR图都表明,Cu 2 O 3的用量在0-1g范围内,不会影响Ca/Na铅基砷硼酸盐氧化物玻璃的非晶态性质,其中存在四个基本结构单元。每个样品(BO 3、BO 4、PbO 4和 AsO 4)。根据使用紫外-可见光谱的光学表征,Cu 2 O 3浓度的增加导致光学能隙减小,同时增加光吸光度、光反射率、等离子体频率、计算的线性和非线性折射率、光导率和光电导率。计算和放射性测量结果表明,随着Cu 2 O 3含量的增加,有效质量数增加,而平均自由程MFP和半值层HVL减少。根据结果,所检查的玻璃可以用作红外滤光片和防护罩。
