Melt quenching technique has been used to fabricate calcium boro-phosphate glasses doped with praseodymium oxide ions. With increased PO content, structural parameters like oxygen molar volume (Vo) and oxygen packing density (OPD) indicate an opposing trend. In addition to optical factors like optical electronegativity, absorption edge, and direct and indirect bandgap values being estimated and discussed, optical absorption spectra have been recorded for all the glasses. The presence of ionic bond behaviour confirms the strong structural and optical property changes caused by the PO content. Using the Phy-X software application, the radiation shielding parameters were investigated. The incorporation of BO, CaCO, and PO offers more number of bridging oxygens which further leads to closely packed nature. Considering the glass sample B0PCM:Pr, the highest linear attenuation coefficient (LAC) is determined. The LAC results showed that at high energy levels, the glass's shielding performance became more consistent. The results of the effective atomic number analysis demonstrated the impact that CaCO has on the glass's shielding effectiveness, with a higher concentration of CaCO improving the material's defence against gamma radiation. For B0PCM:Pr glass, the half value layer (HVL) rises from 2.101 to 3.444 cm at 0.284–1.333 MeV. Certainly, it has been observed that the glass tends to have a smaller HVL when it contains more CaCO with lesser PO content.

用于抗辐射应用的无铅碱性混合硼酸盐玻璃的实验和数值评估

熔融淬火技术已用于制造掺杂氧化镨离子的硼磷酸钙玻璃。随着 PO 含量的增加，氧摩尔体积 (Vo) 和氧填充密度 (OPD) 等结构参数呈现相反的趋势。除了估计和讨论光学电负性、吸收边以及直接和间接带隙值等光学因素外，还记录了所有玻璃的光学吸收光谱。离子键行为的存在证实了 PO 含量引起的强烈结构和光学性质变化。使用 Phy-X 软件应用程序研究了辐射屏蔽参数。 BO、CaCO 和 PO 的结合提供了更多数量的桥接氧，这进一步导致了紧密堆积的性质。考虑玻璃样品 B0PCM:Pr，确定最高线性衰减系数 (LAC)。 LAC 结果表明，在高能量水平下，玻璃的屏蔽性能变得更加一致。有效原子序数分析的结果证明了碳酸钙对玻璃屏蔽效能的影响，较高浓度的碳酸钙提高了材料对伽马辐射的防御能力。对于 B0PCM:Pr 玻璃，半值层 (HVL) 在 0.284–1.333 MeV 处从 2.101 cm 上升到 3.444 cm。当然，据观察，当玻璃含有较多的 CaCO3 和较少的 PO 含量时，玻璃往往具有较小的 HVL。
