Abstract Zinc sulphide (ZnS) nanostructures have been prepared by solvothermal method using ethylenediamine (EDA) as solvent and cetyl trimethyl ammonium bromide (CTAB) as surfactant. The prepared nanostructures were characterized spectroscopically. Transmission electron microscopy (TEM) imaging was done to investigate changes in morphology of ZnS nanostructures prepared with different molar ratios. A distorted square pyramidal geometry with sulfur atoms around the zinc ions was revealed from X-ray diffraction (XRD) pattern and Scanning electron microscopy (SEM) micrograph. Absorbance studies indicate significant blue shift. Enhanced luminescence depicted by photoluminescence (PL) studies predicts applications in optical devices.
