Abstract
We report the formation of well-defined ZnO nanostructures using pulsed-laser fragmentation of Zinc oxide micro-spheres in water condition. The typical morphology of the ZnO nano-particle exhibits hexagonal crystal structure with sides approximately 30nm. The occurrence of an inhomogeneous light intensity distribution on ZnO micro-spheres is responsible for the laser micro-etching/fragmentation process, resulting in the curvilinear arrays of the nano-scaled ZnO hexagonal crystals..
