Abstract

Zinc sulfide (ZnS) nanoparticles were synthesized by the wet chemical method. The crystal structure 
and grain size of the particles were determined, using X-ray diffraction (XRD). The optical properties 
were studied by the Ultraviolet-Visible (UV-Vis) absorption spectrum. The dielectric properties of ZnS
nanoparticles were examined using a HIOKI 3532-50 LCR HITESTER over the frequency range of 50 Hz – 
5 MHz at different temperatures. The variation of the dielectric constant and dielectric loss were 
studied. The dielectric constants of the ZnS nanoparticles are high at low frequencies, and decrease 
rapidly when the frequency is increased. Further, electronic properties like valence electron plasma 
energy, Penn gap, Fermi energy and electronic polarizability of the ZnS nanoparticles, were estimated.
