摘要

The structure and optical characteristics of polyvinyl chloride (PVC) doped with varying concentrations of multiferroic BiNi0.1Fe0.9O3 NPs (nanoparticles) have been investigated. The sol-gel method was employed to prepare multiferroic NPs. The morphology of the generated multiferroic NPs was investigated using the high-resolution transmission electron microscope (HRTEM). Solution casting was used to create PVC/BiNiFeO3 -NPs nanocomposites. The density progressively rises as the amount of multiferroic NPs increases. As the concentration of the Multiferroic dopant rose, the values of Eg decreased from 5.241 ± 0.001 eV to 2.751 ± 0.001 eV and Urbach energy (EU) increased from 0.458 ± 0.001 eV to 41.254 ± 0.001 eV. An increase in multiferroic nano-ferrite concentration resulted in an improvement in the polymer film samples’ refractive index. The suggested samples can be applied for optical and spintronic devices.
