摘要

In this work, a comprehensive investigation of optical features and radiation shielding (γ-ray and neutron) protection properties of the lutetium (III) reinforced calcium lithium borosilicate glasses with the composition B2O3-SiO2-CaO-Li2O-Lu2O3 was presented. The optical band energy (Eg) for direct transition ranged from 3.161 to 3.067 eV, while ranged from 2.984 to 2.866 eV for indirect transition. Urbach's energy (EU) was fluctuated from 0.348 to 0.372 eV. Refractive indices (n) were enhanced as the Lu3+ ion substitution ratio increased. The investigated samples were named Lu-X, and X = 0.0-2.0 mol%. Monte-Carlo code (MCNP) and Phy-X (PSD) were pragmatic to achieve the mentioned aims. The linear (µ) and mass (µm) absorption coefficients followed the order: Lu-0.0 < Lu-0.5 < Lu-1 < Lu-1.5 < Lu-2.0. Lu-2.0 sample possessed the lowest half-/tenth-value layer (HVL, TVL). Within the investigated energy range of the effective atomic number ( \({\text{Z}}_{\text{ef}})\) Z ef ) ) within the range from 14.294-8.048, 21.155-8.645, 26.510-9.230, 30.843-9.809, and 34.410-10.380 for glass samples Lu-0.0, Lu-0.5, Lu-1, Lu-1.5, and Lu-2.0, respectively. The fast neutrons removal cross section of Lu-X samples have values of 0.100, 0.099, 0.099, 0.098, and 0.098 cm−1 for Lu-X glasses where X = 0.0, 0.5, 1.0, 1.5, and 2.0, respectively. The Lu-2.0 sample demonstrated superior γ-ray shielding capability, while the Lu-0.0 sample exhibited the highest neutron shielding capability among the Lu-X glasses. The results validated that Lu-X samples exhibit great potential as effective materials for shielding against γ-ray and neutrons as well as used in optical application.
