In the last decade the synthesis and design of nanoscale ZnO materials gain significant interest due to the variety of possible applications. The present work describes a novel method to obtain flower-like ZnO nanocrystals using a simple solvothermal syntesis assisted by supercritical CO2. The effect of various parameters on the morphology and optical properties of the nanoparticles was investigated. The solid material obtained was investigated for structural information using SEM, XRD. In optimal conditions chrysanthemum like aggregates of ZnO nanorods were obtained as 3D highly ordered structures..
