   The interest about zinc oxide is increasing thanks to its unique chemical and physical properties. Our attention has focused on preparation powder of 1 D nanostructures of ZnO – nanowires with precisely defined morphology include characterization size (length and diameter) and shape controlled in the scanning electron microscopy (SEM). We have compared results of SEM with dynamic light scattering (DLS) technique. We have found that SEM method gives more accurate results. We have proposed transformation process from ZnO nanowires on substrates to ZnO nanowires powder by ultrasound peeling to colloid followed by lyophilization. This method of the mass – production of the ZnO nanowires powder has some advantages: simplicity, cost effective, large-scale and environment friendly.

Keywords: zinc oxide nanowires, hydrothermal growth method, scanning electron microscopy (SEM)
