摘要

The melt-quenching approach was used in this work to create several batches of bismuth zinc borosilicate glasses enriched with different amounts of neodymium (Nd2O3) oxides. Substituting B2O3 with Nd2O3 y increases the density of the resulting glass sample. Upon increasing the concentration of Nd2O3 from 0 to 1.2 mol%, the glass molar volume decreases. The structure of the glasses under study has been examined using a Fourier transform infrared spectrometer. Incorporating Nd-ions into the glass’s network increases the number of non-bridging oxygen (NBO) ions in its internal molecular structure. A broad variety of frequencies was used to study the dielectric properties. The dielectric constant level (εʹ) increases steadily as the amount of Nd2O3 increases. Electrical conductivity (σac) increases with applied frequency. The addition of Nd2O3 causes σac and εʹ to rise due to the breakdown of the glass network’s structure and the rise in (NBO). The energy absorption (EABF) and exposure building factor (EBF) for the glasses under investigation have been determined at deep penetration levels of 0.5–40 mfp in photon energy extends between 0.015 and 10 MeV. Fast neutron removal sectionals (FNRCS) utilizing the G-P fitting method and a glasses’ equivalent atomic numbers Zeq, EBF, and EABF were computed using Phy-X/PSD software. The reported EBF and EABF have been displayed to rely on penetration depths, photon energy, and the glass sample’s Nd2O3 mol% content. Compared to other samples, Nd-1.2 glass has been found to offer better gamma-ray shielding. The results of this study may also be useful for radiation shielding applications in nuclear engineering, industry, and health.
