Fabrication of Zinc Oxide Nanoparticles by pulsed laser ablation in liquid - PLAL and Study their physical Properties

Abstract

ZnO NPs are manufactured using pulsed laser ablation in double distilled water (DDW). Nd:Yag laser used as a source of energy for this research by immersing the zinc-target in DDW water. The glass container with laser pulses was rotated to prevent etching effect and getting homogenous distribution particles. By changing the parameters (laser energy and number of pulses), the results were collected and examined using an ultra violet-visible spectrum and electron scanning microscope. The calculations revealed the colloidal spherical shape and the homogeneous structure for the ZnO NPs. The band gap plot display varies in the band gap proportional with particle size, this result agree with effective mass model.
