Photon and neutron shielding factors and elastic moduli of phosphate glass doped with Tm3+ ions (abbreviated as PPKANT glasses) have been analyzed. MCNP-5 simulation code, and Phy-X/PSD software have been utilized to estimate the gamma rays and neutron shielding capacity. Furthermore, Makishima and Mackenzie’s theory has been performed to calculate elastic moduli. Young’s modulus, bulk modulus, and shear modulus have been varied from 40.71 to 43.62 GPa, 28.01 to 30.65 GPa, and 16.18 to 17.27 GPa, respectively. Poisson’s ratio changed from 0.257 for PPKANT0.1 glass to 0.263 for PPKANT4 glass. At low gamma photon energy (0.015 meV), the LAC increased with the increase of Tm3+ content (LAC = 155.54 and 170.18 cm−1 for glass samples PPKANT0.1 and PPKANT4, respectively). At high energy (15 MeV), the LAC changed from 0.118 to 0.124 cm−1 for PPKANT0.1 to PPKANT4. The highest values of the HVL decreased from 5.734 to 5.570 cm. The trend of MFP was like the HVL trend. At 15 MeV, the values of the EBF and EABF were rapidly increased with the increase in the penetration depth (PD), especially for PD > 20 mfp. The lowest ∑R was achieved for glasses PPKANT4 with 4 mol % Tm2O3, where ∑R = 0.02561 cm2g−1. The investigated PPKANT glasses can be considered good neutron and photon shields compared to some traditional radiation shielding materials.

Tm3+ 离子掺杂磷酸盐玻璃：核屏蔽能力和弹性模量

分析了掺杂Tm3+离子的磷酸盐玻璃（简称PPKANT玻璃）的光子和中子屏蔽因子和弹性模量。MCNP-5 仿真代码和 Phy-X/PSD 软件已被用于估计伽马射线和中子屏蔽能力。此外，Makishima 和 Mackenzie 的理论已用于计算弹性模量。杨氏模量、体积模量和剪切模量分别在 40.71 至 43.62 GPa、28.01 至 30.65 GPa 和 16.18 至 17.27 GPa 之间变化。泊松比从 PPKANT0.1 玻璃的 0.257 变为 PPKANT4 玻璃的 0.263。在低伽马光子能量 (0.015 meV) 下，LAC 随 Tm3+ 含量的增加而增加（玻璃样品 PPKANT0.1 和 PPKANT4 的 LAC 分别为 155.54 和 170.18 cm-1）。在高能量（15 MeV）下，PPKANT0 的 LAC 从 0.118 变为 0.124 cm-1。1 到 PPKANT4。HVL 的最高值从 5.734 下降到 5.570 cm。MFP 的趋势就像 HVL 的趋势。在 15 MeV 时，EBF 和 EABF 的值随着穿透深度 (PD) 的增加而迅速增加，尤其是对于 PD > 20 mfp。使用 4 mol% Tm2O3 的 PPKANT4 玻璃实现了最低的 ∑R，其中 ∑R = 0.02561 cm2g-1。与一些传统的辐射屏蔽材料相比，研究的 PPKANT 玻璃可以被认为是良好的中子和光子屏蔽。
