Abstract
Structural, optical, mechanical and gamma-ray shielding of newly prepared cadmium biso-borate transparent glasses with the form (70-x)B2O3-15ZnO-10BaO-5CdO-xBi(2)O(3): x = 0, 2, 4, 8, and 12 mol% glasses were investigated. Glasses have been fabricated by the quenching conventional process and named as Bi-0 (x = 0), Bi-2 (x = 2), Bi-4 (x = 4), Bi-8 (x = 8), and Bi-12 (x = 12). Moreover, radiation shielding capability of these glasses has been performed via XCOM program and FLUKA simulation code. The density of the fabricated Bi-glasses was enhanced from 3.26 to 3.95 g/cm(3) and molar volume was also increased from 25.35 to 33.00 cm(3)/mol was with the increase of Bi2O3 content. The indirect optical band gap was decreased from 2.49 to 2.13 eV and values of Urbach energy (E-urbach) were increased from 0.364 to 0.516 eV. The linear attenuation coefficient (LAC) values were the highest at lowest energy, for example, 58.42, 67.33, 76.47, 96.39, and 118.11 (cm(-1)) for Bi-0, Bi-2, Bi-4, Bi-8, and Bi-12 glasses, respectively at 0.015 MeV. LAC and mass attenuation coefficient (MAC) values were followed the trend as: (Bi-0)(LAC,MAC) < (Bi-2)(LAC,MAC) < (Bi-4)(LAC,MAC) < (Bi-8)(LAC,MAC) < (Bi-12)(LAC,MAC). Values of the half value layer (X-1/2) and mean free path (lambda) of the fabricated Bi-glasses were have the same trend as (Bi-0) (X1/2, lambda) > (Bi-2) (X1/2, lambda) > (Bi-4) (X1/2, lambda) > (Bi-8) (X1/2, lambda) > (Bi-12) (X1/2, lambda). The Bi-0 glass has the lowest Z(eff) values while the Bi-12 glass has highest Z(eff) values within selected photon energy. The kinetic properties (Y, K, G, and L) were enhanced with the increased of the Bi2O3 content in the Bi-glasses. Results revealed that the fabricated glasses have better radiation shielding competences compared to several of other conventional materials.
