Polymer nanocomposite based on polyvinyl alcohol (PVA) and lead sulfide (PbS) in the average radius of (1.88-2.23) nm, have been synthesized using the chemical reduction rote and solution casting technique for different concentrations of PbS. The characterization of the polymer nanocomposite films were carried out using UVvisible spectroscopy, SEM, and XRD. The effect of various concentration of PbS NP on the optical properties of the composite has been studied to understand the optimum conditions for the synthesis process. The nanocomposite film shows high UV and visible light absorptions in the wavelength range of (200-500) nm, which correspond to the characteristics of the PbS NPs. The significant decreasing trend of the direct allowed band gap of the nanocomposite was observed upon increasing the Pb source concentration, from (6.27 eV) for pure PVA to (2.34 eV) for 0.04 M PbS concentration, which is much higher than the energy gap of bulk PbS value (0.41 eV). The calculated values of the static refractive index of Cauchy dispersion model were in the range of (1.09-1.20).X-ray diffraction analysis confirmed the cubic nanocrystalline PbS phase formation.

“…The weak band observed at 1628 cm −1 is attributed to the bending vibration modes of water (H-O-H) [12], which might be due to the aqueous medium used to synthesize the PbS nanopowder. The peaks at 1112 cm −1 and 606 cm −1 are due to heteropolar diatomic molecules of lead sulphide [13]. Besides, no strong bands associated with Pb-S stretching and bending vibrations are observed in the FT-IR spectrum as the bond associated with Pb-S is mainly electrovalent in nature [14].…”

Lead sulphide (PbS) nanopowder was synthesized by a simple soft chemical route using lead nitrate and thiourea as precursor salts. The as-synthesized nanopowder was characterized by XRD, SEM, EDX, FT-IR, PL, Raman and magnetic measurements. XRD studies reveal the polycrystalline nature of the powder. The powder exhibits face-centered cubic structure with a strong (2 0 0) preferential orientation. The presence of Pb and S in the powder is confirmed by energy dispersive X-ray analysis. The peaks observed at 1112 cm −1 and at 606 cm −1 in the FT-IR spectrum are related to heteropolar diatomic molecules of PbS. The Raman peak shift at 173 cm −1 might have originated from the combination of longitudinal and transverse acoustic phonon modes associated with PbS crystal. The M-H loop confirms the paramagnetic nature of the as-synthesized PbS nanopowder. The nanopowder has significant antimicrobial activity against certain bacteria and fungi strains which make it suitable as antimicrobial agent against pathogenic microorganisms.

“…Water pollution due to dyeing industry is the matter of great concern since large quantity of effluent is discharged into the water bodies. [19][20][21] The photocatalytic behavior of Undoped and Ni doped ZnS nano particles on the degradation of Methylene Blue, a widely used dye by the textile industries was carried out using ZnS, and Ni doped ZnS nano particles and the degradation percentage was calculated. 0.030 g of samples were suspended in 4 beakers each of 20ml methylene blue dye stock solution (5 ppm) and were irradiated simultaneously with a 8W UV lamp placed at a distance of 4.0 cm.…”

Nanoparticles of Undoped ZnS, Ni-Doped-ZnS, were prepared by using Wet Chemical-Synthesis method. The structural and morphological characterizations of nanoparticles were done using X-Ray powder Diffraction (XRD), Scanning Electron Microscope (SEM) and EDAX. The optical properties of the as prepared samples were analyzed by UV-VIS Spectrophotometry and Spectrofluorometer. The average crystalline size of as-synthesized photocatalysts calculated using the Debye-Scherer formula and found to vary from 20nm to 25nm. Photocatalytic activities of Undoped and Ni doped ZnS were evaluated by decolorization of Methylene Blue in aqueous solution under UV light irradiation. It was found that the Ni doped ZnS nano particles exhibits higher degradation efficiency than the Undoped ZnS nano particles.
