Abstract

In this work usede pulsed laser ablation in liquid to produced congenial nanoparticles, is a direct, precision and easy method. A quasi like spherical NiO NPs were utilized a 1064nm Nd:YAG laser, working with 700 J/pulse and altered number pulses (50, 100 and 150 pulses). Impacts laser pulses on the features of NiO NPs were been deliberated briefly. FTIR spectra resemble the establishment of Ni-O band. The concentration of NiO nanoparticles increased when the number of laser pulses increased. The optical absorption exhibit a blue shift when the number of laser pulses decreased, with gaps are changing from 3.65 to 3.8 eV depending on number of laser pulses.
