Polyvinyl alcohol (PVA)/polyvinylpyrrolidone (PVP; weight 7:3) polymer blends doped with different ratios (1 wt%, 3 wt%, 5 wt%, and 10 wt%) from nano SnS 2 /Fe are developed using casting and thermolysis procedures. Rietveld analysis showed that Fe is incorporated into the SnS 2 lattice forming a single hexagonal phase with an average crystallite size of 6 nm along [00l] direction and 15 nm along [h00] direction. X-ray diffraction together with Fourier transform infrared data is used to examine the homogeneity distribution of the nanofiller over the blend matrix. The effect of doping on the absorbance, transmittance, extinction coefficient, refractive index, direct and indirect optical band gaps, and other dispersion parameters of the blend is studied in detail.The nature of electronic transitions in the different blends was determined using Tauc's relation and the dielectric loss parameter. As the weight concentrations of SnS 2 /Fe dopants increased, the nonlinear optical parameters are increased relative to the undoped PVA/PVP polymer blend. The influence of the different excitation wavelengths and the amount of nanofillers on the fluorescence spectra from different blends are also investigated.

“…These applications include optoelectronics, solar cells, LEDs, electrolytes, superconductors, and others. [ 7,10–16 ] Among these polymers, polyvinyl alcohol (PVA) is preferable since it has many novel characteristics over others. Some of its features: biocompatibility, water‐solubility, and environmental friendliness.…”

The effect of iron oxide nanoparticles (Fe2O3 NPs) content on the structural and optical parameters of polyvinyl alcohol/graphene (PVA/G) blend has been investigated. Fe2O3 NPs were synthesized by the hydrothermal procedure. Nanocomposite (NC) films of PVA/G filled with different amounts of Fe2O3 NPs were equipped using the solution casting technique. The surface morphology, structural, and optical properties were examined by scanning electron microscope (SEM), X‐ray diffraction (XRD), and ultraviolet‐visible‐near‐IR (UV‐Vis‐NIR) spectrophotometry techniques, respectively. SEM micrographs reveal the homogenous distribution of Fe2O3 NPs in the PVA/G matrix. The XRD analysis exhibits the formulation of the hematite phase of Fe2O3 NPs and the semi‐crystalline nature of PVA/G NC films. The UV‐Vis‐NIR data analysis shows that the optical properties of the PVA/G blend could be tailored via Fe2O3 NPs filling. Wemple–DiDomenico model is utilized to explore the dispersion parameters of the prepared NCs. A significant effect of Fe2O3 NPs filling is realized on the oscillator and dispersion energies, infinite refractive index, dielectric constant, average oscillator strength and the lattice dielectric constant of the NC films. PVA/G filled Fe2O3 NPs are suggested for different optical and storage applications.

“…Polymer-based nanocomposites attracted much attention in recent years, owing to their good properties and potential applications in optoelectronic fields [1][2][3]. Moreover, mixing two or more polymers to form a blended polymer opens new fields of applications, due to the new properties that emerged [4,5]. PVA has been investigated intensively owing to its good film producing and physical characteristics, high hydrophilicity, processability and good chemical resistance [6,7].…”

Undoped and doped with nano-ZnO (Zn 0.9 X 0.1 O, X = Co, Cu and Mn) blended polymers (70% polyvinyl alcohol/30% polyvinyl pyrrolidone) were formed using solid-state reaction and casting methods. X-ray diffraction measurements were used to examine the incorporation of the nanofiller into the polymer matrix. Rietveld analysis showed an average crystallite size of 20 nm for ZnO with a little change upon doping Co, Cu, or Mn. The variations in the absorbance, extinction coefficient, refractive index, direct optical band gap energy, the single-oscillator energy, the oscillator strength and static refractive index of the blend with the nanofiller were studied in detail. The optical bandgap of the pristine blend, 4.97 eV, was reduced upon doping reaching a minimum of 4.82 eV for pure ZnO. The obtained values of electric characteristics and nonlinear optical properties are affected by the kind of dopant and the value of wavelength used. The reduction obtained in the optical band gap can nominate the doped blended polymers to be used as an absorbing layer in a solar cell to improve the efficiency of photovoltaic devices. Also, the enhancement of the nonlinear parameters nominates them to be applied in different nonlinear optical and photonic applications. The emitted fluorescence spectra depended on the excitation wavelength and the kind of dopants.
