In this paper, we prepared ZnO nano-particles by using pulsed laser ablation in water. ZnO particles are dispersed in pure water as a target material of laser ablation. We irradiated the ZnO particles in water with YAG laser with different wavelengths to investigate the effects of photon energy on the nano-particle formation. We measured both atomic composition of ZnO and crystallinity of the fabricated nano-particles by EDX and XRD. We also observed ZnO nano-particles by TEM. The averaged diameter of ZnO nano-particles was 6 nm.
