Abstract

In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributions, with particle sizes (80.76 nm to 102.54nm )and shape were measured by using SEM shows spherical shape while the composing of the prepared nanoparticle were determined by X-ray, UV-Visible spectroscopy has been employed for the optical properties, the UV-VIS spectrum of the produced solution shows red shifted in the peak position with the laser ablation energy. The produced collide was a good stable.
