The size of the particles were determined by X-ray Diffraction(XRD) and scanning electron microscopy(SEM) and was compared to that of bulk ZnS. The SEM images revealed that bulk sized ZnS and ZnS nanoparticles were of different origin, structure and size Further studies were carried out to determine the difference in electrical properties (dielectric constant, dissipation factor, A.C. conductivity, resistivity) of these materials due to their size difference. Keywords: Zinc Sulphide ,XRD,SEM, nanoparticles,electrical properties. {Citation: Sutapa Ganguly, Kumaresh Halder, Nur Amin Haque, Sukhen Das, Sujata G Dastidar.
