Abstract :
In this paper, zinc oxide (ZnO) nanoparticles were
prepared by laser ablation of Zinc (purity of 99/99 %) target.
The effect of solvents, methanol and distilled water on the
characterization of ZnO has been investigated. The beam of a
Q-switched Nd: Yag laser with the length wave of 1064 nm
and pulse duration of 6 ns was used. ZnO nanoparticles which
were produced in distilled water and methanol were characterized by transmission electron microscopy, X-ray diffraction (XRD) and the optical absorption spectroscopy–
ultraviolet (UV–VIS-IR). The XRD results showed that the
ZnO nanoparticles have a hexagonal crystal structure. Different size of ZnO nanoparticles were formed because of
different environment of laser pulse generated.
