摘要

The present project purposes to generate of ZnO/Mn3O4/MnO nanocomposite doped polyvinyl chloride (PVC)/ polyethylene oxide (PEO) blended polymers as innovative materials that can be suitable in a diversity of optoelectronic and photocatalytic uses. The structure, optical and fluorescence (FL) features of PVC/PEO/wt% ZnO/Mn3O4/MnO blended polymers were examined. The minimal direct and indirect bandgap energies of 4.03 eV and 3.58 eV, respectively, were achieved when the ZnO/Mn3O4/MnO nanocomposite concentration reached 4 wt% in the doped blended polymer. The sample containing 4 wt% ZnO/Mn3O4/MnO displayed the greatest refractive index value at a wavelength of 600 nm. The optical dispersion parameters for all blended polymers were investigated using Wemple-DiDomenico model. The incorporation of ZnO/Mn3O4/MnO into the PVC/PEO matrix yields significantly elevated optical dielectric energy constant and energy loss function values associated with the pure PVC/PEO film. The peak nonlinear optical parameter values were obtained in the visible spectrum when PVC/PEO was filled with ZnO/Mn3O4/MnO. Different theoretical methods were used to determine the refractive index and nonlinear optical parameters based on the obtained optical band gap energies. The FL data of filled samples decreased as PVC/PEO was infused with ZnO/Mn3O4/MnO. The CIE chromaticity coordinates of all samples were calculated.
