Beschreibung
Zusammenfassung:[Display omitted] •Spherical and flake/spherical shaped ZnS nanostructures were prepared by the hydrothermal method.•The sphalerite and wurtzite crystal structure of the ZnS samples has been confirmed in the XRD analysis.•In the SEM and TEM analysis, the flake/spherical particles of the S-ZS samples were observed.•Studies of UV and FL showed better optical absorption and luminescence behavior of the S-ZS sample.•The photocatalytic degradation of the MO dye using ZS and S-ZS samples has been studied. The mixed morphology of semiconducting metal sulfide nanostructured materials has been the hotspot of research. In this paper, we have reported the sugar assisted hydrothermal method, applied to prepare spherical/flake surface morphology of ZnS nanostructures. The crystal structure, surface morphology, light absorption, energy gap, emission peak, surface defects and photocatalytic properties of ZnS materials have been examined through the XRD, SEM, TEM, UV–visible, FL and photocatalytic studies. A solution of methyl orange dye is mixed with prepared ZnS samples under the illumination of UV-light; the photocatalytic degradation absorption, and efficiency have been estimated from the optical spectra of this mixtures.
