摘要

In the current work, an amount of multiferroic BiNi0.5Fe0.5O3 nanoparticles was prepared via the sol-gel method. Then, glass samples with multiferroic with chemical formula 70B2O3-10Na2O-10PbO-10ZnO-x(BiNi0.5Fe0.5O3): x = 0.0 (BNF0.0) − 1.0 (BNF1.0) mol.% were prepared by the melt quenching technique. XRD of BiNi0.5Fe0.5O3, physical and optical characteristics, and γ-ray attenuation performance were investigated. Via Scherrer equation, the crystallite sizes (D) of the prepared BiNi0.5Fe0.5O3 was 29 nm. The density (ρ) increased from 2.9329 ± 0.0001 g/cm3 for BNF0.0 glass sample to 3.124 ± 0.0001 g/cm3 for BNF1.0 glass sample. The molar volume (Vm) reduced from 28.3218 ± 0.0001 (cm3/mol) to 27.2217 ± 0.0001 (cm3/mol). The direct optical gap (Eg) reduced from 3.18 ± 0.01 eV for the BNF0.0 sample with free BiNi0.5Fe0.5O3 to 2.45 ± 0.01 eV for the BNF1.0 sample with the highest content of BiNi0.5Fe0.5O3. Mass (MAC) values of BNFx glasses increased with the insertion of BiNi0.5Fe0.5O3 in the glass networks as [MAC]BNF1.0 > [MAC]BNF0.3 > [MAC]BNF0.4 > [MAC]BNF0.2 > [MAC]BNF0.0. Values of half-(hVL) value layer reduced as [HVL]BNF1.0 < [HVL]BNF0.8 < [HVL]BNF0.4 < [HVL]BNF0.2 < [HVL]BNF0.0. The findings suggest that the investigated BNFx glasses are promising materials in optical and radiation attenuation fields.
