Abstract

PrZn-glasses were synthesized with nominal compositions of (60-x)B2O3 + 24.5BaF + 0.5PrO + 15NaO + xZnO: x = 0 (PrZn0)–10(PrZn10). Physical, linear/nonlinear optical characteristics as well as γ-ray protection competence of the prepared glasses have been investigated. The density changed from 3.31 to 3.61 3.31 g/cm3, while the molar volume (Vm) reduced from 29.95 g/mol of PrZn0 sample to 27.80 g/mol for samples PrZn0 and PrZn10. UV–Vis measurements of the proposed glasses showed that the absorption bands corresponding to 445, 469, 483, and 589 nm are correlated to electronic transitions of 3H4 → 3P2, 3H4 → 3P1, 3H4 → 3P0, and 3H4 → 1D2 exciting levels. The optical energy gap (Eg) for PrZn0 sample was 2.864 eV, while for PrZn10 sample was 2.693 eV. The values of n were increased gradually with ZnO additives. Molar refraction (Rm), electronic polarizability (αm), reflection loss (RL) and optical transmission (T) changed significantly as ZnO ratios changed in the glass networks. The sample PrZn10 possessed the maximum mass-attenuation coefficient (MAC). The linear-attenuation (LAC) values differed from (86.050 to 111.546) cm−1 (at 0.015 MeV) and from (0.094 to 0.106) cm−1 (at 15 MeV) for PrZn0 and PrZn10 samples. The half- value layers (HVLs) of the suggested glasses were less than values of others (ordinary concrete and glasses). Therefore, the suggested glasses in the present work can be applied in optical application and as γ-ray attenuation materials.

ZnO增强B2O3-BaF2-Pr6O11-Na2O玻璃的作用:合成、物理、线性光学性能和γ射线衰减效果
PrZn 玻璃的合成标称成分为 (60-x)B2O3 + 24.5BaF + 0.5PrO + 15NaO + xZnO:x = 0 (PrZn0)-10(PrZn10) 。研究了所制备玻璃的物理、线性/非线性光学特性以及γ射线防护能力。密度从 3.31 克/立方厘米变为 3.61 3.31 克/立方厘米,摩尔体积(Vm)从 PrZn0 样品的 29.95 克/摩尔变为 PrZn0 和 PrZn10 样品的 27.80 克/摩尔。对所提出的玻璃进行的紫外可见光谱测量表明,对应于 445、469、483 和 589 纳米波长的吸收带与 3H4→3P2、3H4→3P1、3H4→3P0 和 3H4→1D2 激发水平的电子跃迁相关。PrZn0 样品的光能隙(Eg)为 2.864 eV,而 PrZn10 样品的光能隙(Eg)为 2.693 eV。n 值随着氧化锌添加剂的增加而逐渐增大。摩尔折射率(Rm)、电子偏振率(αm)、反射损耗(RL)和光透射率(T)随着玻璃网络中氧化锌比例的变化而发生显著变化。样品 PrZn10 具有最大的质量衰减系数(MAC)。PrZn0 和 PrZn10 样品的线性衰减 (LAC) 值分别为(86.050 至 111.546)cm-1(0.015 MeV 时)和(0.094 至 0.106)cm-1(15 MeV 时)。所建议的玻璃的半值层(HVLs)小于其他玻璃(普通混凝土和玻璃)。因此,本研究中提出的玻璃可用于光学应用和作为γ射线衰减材料。
