Zinc Sulfide (ZnS) nanoparticles were successfully synthesized by chemical co-precipitation method using Zinc nitrate and sodium sulfide as a precursor material. Methacrylic acid was used as capping agent. The highly stable colloidal ZnS nanoparticles have been prepared at room temperature. The sample were characterized by X-ray diffraction (XRD), UV visible absorption spectroscopy, band gap measured by UV-Visible absorbance spectrum. In the XRD pattern of samples, there is no change in the cubic zincblende structure. The crystallite size of as prepared nanoparticles is found to be in the 7 nm range. The value of optical band gap has been found to be in the range 3.58 eV.
