The purpose of this study was to characterize the structural, optical, and physical properties of various kinds of glasses based on the 50TeO2–30B2O3-(20-x)Li2O-xCeO2 system (x = 0, 0.5, 1, 2, 4, 5, 10, 15, 20). Consequently, ten glass samples were produced by melting-annealing. Calculations of the densities of the synthesized glasses were performed using the Archimedes technique. The sample's structural, optical, physical, and radiation interaction properties were determined using XRD analysis, Raman spectroscopy, and advanced modelling techniques with FLUKA code, yielding optical band gap, refractive index, and Urbach energy values. By increasing the CeO2 reinforcement from 0 to 20 mol %, the glass densities rose from 4.0614 to 4.7519 g cm−3. The transmittance spectra of TBLC glasses were found in the range of 200–1100 nm. Our findings showed that the lowest Urbach energy belonged to the TBLC1 sample, and the highest Urbach energy belonged to the TBLC20 sample. When the CeO2 ratio was raised, the optical transmittance and absorption characteristics changed nearly monotonically, suggesting that these qualities may be calculated and controlled using the CeO2 additive, as shown in this experiment. By substituting CeO2 for Li2O inside the structure, it was possible to substantially enhance the optical band gap. Additionally, at simulated energies greater than 0.02 MeV, the gamma-ray linear attenuation coefficient rises monotonically with CeO2 reinforcement. Consequently, linear attenuation coefficients were reported as 125.843 cm−1, 127.601 cm−1, 129.211 cm−1, 132.312 cm−1, 135.166 cm−1, 138.705 cm−1, 141.288 cm−1, 156.690 cm−1, 172.393 cm−1, 186.811 cm−1 for TBLC0, TBLC0.5, TBLC1, TBLC2, TBLC3, TBLC4, TBLC5, TBL10, TBLC15 and TBLC20 at 0.015 MeV, respectively. It can be concluded that combination of high-concentration CeO2 and TeO2–B2O3 glass is an excellent synergetic tool for combining structural, optical, and radiation properties when combined with other materials.

氧化铈 (IV) 增强锂硼硅酸盐玻璃:通过物理、光学、结构和辐射屏蔽特性进行的表征研究

本研究的目的是表征基于 50TeO 2 –30B 2 O 3 -(20-x)Li 2 O-xCeO 2系统 (x = 0, 0.5 , 1, 2, 4, 5, 10, 15, 20)。因此,通过熔融退火生产了十个玻璃样品。使用阿基米德技术计算合成玻璃的密度。样品的结构、光学、物理和辐射相互作用特性是使用 XRD 分析、拉曼光谱和具有 FLUKA 代码的高级建模技术确定的,产生光学带隙、折射率和 Urbach 能量值。通过增加 CeO 2从 0 到 20 mol % 的增强,玻璃密度从 4.0614 上升到 4.7519 g cm -3。TBLC 玻璃的透射光谱范围为 200-1100 nm。我们的研究结果表明,最低的 Urbach 能量属于 TBLC1 样品,最高的 Urbach 能量属于 TBLC20 样品。当 CeO 2比率增加时,光学透射率和吸收特性几乎单调变化,这表明可以使用 CeO 2添加剂计算和控制这些质量,如本实验所示。通过用CeO 2代替Li 2O 在结构内部,可以显着提高光学带隙。此外,在大于 0.02 MeV 的模拟能量下,伽马射线线性衰减系数随着 CeO 2增强而单调上升。因此,线性衰减系数被报告为125.843 cm -1、127.601 cm -1、129.211 cm -1、132.312 cm -1、135.166 cm -1、138.705 cm -1、141.2981 cm -1、6916 cm -1、141.2816 cm -1−1 , 186.811 厘米−1对于 TBLC0、TBLC0.5、TBLC1、TBLC2、TBLC3、TBLC4、TBLC5、TBL10、TBLC15 和 TBLC20,分别为 0.015 MeV。可以得出结论,当与其他材料结合时,高浓度 CeO 2和 TeO 2 –B 2 O 3玻璃的组合是结合结构、光学和辐射特性的极好协同工具。
