Influence of the capping agent polyvinyl alcohol and doping of Mn2+ ions on the structural, optical and morphology of the nanoparticles have been studied using X-ray diffraction, UV–Vis spectrometer, photoluminescence, Fourier transform infrared spectrometer, high-resolution electron microscope and atomic force microscope. All the prepared samples possess cubic sphalerite crystal structure with lattice constant a = 5.33 Å. The size of the particles is found to be within 2–6 nm for all the cases. It has been observed that the particle size of the ZnS nanoparticle decreases when capped with polyvinyl alcohol and doped with Mn2+. Fourier transform infrared spectrum of the samples strongly supports the formation of ZnS/PVA and ZnS:Mn2+.
