Abstract


PVC/FeCr2O4/x wt% tetrapropylammonium iodide (TPAI, x = 0, 2.5, 5, 10, 20) polymers were prepared using casting and sol gel methods. Rietveld refinement was used to determine the structural and microstructural properties of FeCr2O4 nanofiller. XRD, FTIR, and SEM techniques were applied to explore the effect of fillers on the structural features of PVC polymer. The effect of FeCr2O4 and/or TPAI on the linear/nonlinear optical properties of PVC was explored. Absorbance was obviously enhanced, and transmittance reduced in the range 200–450 nm upon doping with TPAM. The refractive index and reflectance were increased by loading FeCr2O4. The direct (4.25 eV) and indirect (4.1 eV) bandgap values of the pure PVC were reduced to 4.21 and 3.95 eV upon loading with FeCr2O4; both reduced further, but irregularly, as the amount of TPAI increased attaining lowest values 3.11 and 2.62 eV for TPAI content 2.5 wt%. The optical conductivity and the dielectric constant were greatly enhanced by TPAI doping, while the nonlinear optical parameters were improved by FeCr2O4 loading. Under different excitation wavelengths, the fluorescence intensity was quenched upon loading FeCr2O4, then reduced a little by adding TPAI; the corresponding CIE chromaticity diagrams were obtained.
