Abstract

Nanosized Nickel particles have been synthesized by chemical reduction method. The structure, morphology and optical properties of the as-synthesized Nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDXS) and UV-visible absorption spectrophotometer. XRD studies indicated that the as-synthesized Nanoparticles were pure crystalline nickel with a face- centered cubic (FCC) structure. SEM micrographs reveal that the Nanoparticles are mostly spherical with size around 17.97nm. EDXS analysis confirmed the presence of nickel Nanoparticles. The quantum size confinement of the crystallites is evident from the blue shift of the absorption edge in the UV-visible absorption spectrum..
