摘要

研究了掺杂不同浓度的多铁性BiNi0.1Fe0.9O3纳米粒子的聚氯乙烯（PVC）的结构和光学特性。采用溶胶-凝胶法制备了多铁NPs。利用高分辨率透射电镜（HRTEM）研究了合成的多铁NPs的形貌。采用溶液铸造法制备PVC/BiNiFeO3 -NPs纳米复合材料。随着多铁NPs数量的增加，密度逐渐增加。随着多铁掺杂浓度的增加，Eg值从5.241±0.001 eV下降到2.751±0.001 eV，乌尔巴赫能（EU）从0.458±0.001 eV上升到41.254±0.001 eV。多铁纳米铁氧体浓度的增加导致聚合物薄膜样品折射率的改善。所建议的样品可用于光学和自旋电子器件。

Optical properties of PVC nanocomposites based on synthesized multiferroic nanoparticles

The structure and optical characteristics of polyvinyl chloride (PVC) doped with varying concentrations of multiferroic BiNi_0.1Fe_0.9O₃ 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 E_g decreased from 5.241 ± 0.001 eV to 2.751 ± 0.001 eV and Urbach energy (E_U) 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.
