Preparation of nickel oxide nanoparticles prepared by laser ablation in water

Abstract

Quasi-spherical Nickel oxide based nanomaterial was prepared utilized Nd: YAG laser and different laser energy (500, 600 and 700 mJ/pulse). Powers of laser parameters on the characteristics of NiO nanomaterial prepared using laser ablation in water have been discussed briefly. FTIR measurements conform to the formation of the Ni-O band. The result of the optical absorption exhibit shifted to smaller wavelength, as the laser energy decreased. The transition has direct with band gap are (3.65-3.8) eV rely on laser energies.
