Zinc oxide nanoparticles formation utilizing one step laser ablation in DIW

Nanoparticles production via pulsed laser ablation in water has essential advantage benefit compared to normal approaches, such as the purity and stability of the assembled nanoparticles vaporizers and colloids. Here, in this study zinc oxide (ZnO) nanoparticles have produced in deionized water using laser ablation, and the effect of different laser pulses (25–125pulse) on characterization was investigated. The XRD result found that ZnO with hexagonal structure. The absorption spectra have most absorbance at UV region with intensity increased as a number of pulses increases. FTIR prove the chemical bonding between molecules in ZnO colloidal. SEM image viewed that shape of ZnO NPs varied from irregular spherical shape to nanorod then finally cracking, as a result to increase the number of pulses to become in nanosize scale.
