Abstract: Zinc sulfide (ZnS) nanoparticles were synthesized using chemical co-precipitation method. The structural and morphological properties of these particles were studied by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The crystallite sizes calculated from XRD patterns were 2.8nm and 29nm of as prepared sphalerite and annealed wurtzite ZnS particles respectively. UV-visible absorption spectroscopy was used to calculate absorption edges which were found at 211nm for as prepared and 262 nm for annealed ZnS nanoparticles. These absorption edges were shifted towards lower wavelengths compared to bulk ZnS (337nm). The impedance analysis showed that electrical resistance of annealed sample is decreased as compared to as prepared sample.
