Our interest is based on the low cost ZnO nanorods mass production using chemical methods. In this study we focus on correlation between morphology, crystalographic structure and defects in the hedgehog -like ZnO nanostructures prepared by the hydrothermal growth without seeding layer. The lack of the seeding layer leads to the random growth of low quality nanocrystals as shown by SEM, XRD and Raman spectroscopy. The localized defect states below the optical absorption edge were characterized by the photoluminescence and optical absorption spectroscopy in a broad spectral range from UV to IR.
