Herein, we report the e ffect of calcination on the structural and optical properties of nanocrystalline NiO. NiO nanoparticles were synthesized by chemical precipitation method using nickel nitrate hexahydrate and ammonium carbonate. Thermogravimetric analysis was done to determine the thermal behavior of the precursor. The samples were characterized by X-ray di raction (XRD), energy dispersive X-ray analysis (EDAX), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), UV-visible and photoluminescence (PL) spectroscopy. Crystallite size and lattice strain on peak broadening of NiO nanoparticles have been studied using Williamson-Hall (WH) analysis. Significan modi cations were observed in the crystallite size, absorption spectra and photoluminescence intensity due to calcination. The desired structural and optical properties of NiO nanoparticle make it as a promising material for optoelectronic applications.
Keywords: nickel oxide nanoparticles, chemical precipitation, crystallite size, optical band gap.
