Detoxification of dye contaminated water by Mn$^{2+}$-doped ZnS nanostructures

[摘要] Chemical co-precipitation route was successfully employed to synthesize polyethylene glycol-coated pure and doped Zn$_{1−x}$Mn$_x$S (0 ≤ x ≤ 0.1) nanoparticles. The crystallographic and morphological analyses have been done by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. The formation of cubic crystal structure and quasi-spherical morphology has been revealed by XRD and TEM, respectively. The optical analyses have been done by UV–Vis absorption spectroscopy and energy resolved photoluminescence spectroscopy. Energy dispersive X-ray spectroscopy study has been carried to analyse the elemental composition. The doping concentration dependent photo-catalytic activity was checked to analyse the photo-catalytic potential of Zn$_{1−x}$Mn$_x$S nanoparticles under UV irradiation.
