Abstract
Urania nanostructures were synthesized by a facile, which is a simple and clean and straightforward deposition method, for two different deposition time durations. The morphology and structures of the products were characterized by the X-ray diffraction analysis (XRD) and Scanning Electronic Microscopy (SEM). The SEM images indicated that the morphology of the synthesized samples for 10 minutes was composed of a coin-like structure with a nano-scale dimension in a narrow- size distribution. The results indicated that the deposition time affects the morphology while it does not affect the structure. The XRD results identified the sample structures as UO2 crystal. The chemical composition of different points of the sample surface was determined by the energy dispersive spectroscopy (EDS) technique and the results clarified that the samples have a homogeneous composition of uranium oxide. The synergistic properties of the substrate surface, and uranium ions are responsible for the formation of an outstanding and a novel structure.
