Hierarchical Assembly of Inorganic Nanostructure Building Blocks to Octahedral Superstructures – A True Template-Free Self-Assembly
Journal Article

· Nanotechnology, 18(7):075303
Time dependent size and shape evolution of nanomaterials has gained a significant interest. A room temperature, template free, wet chemical synthesis of ceria nanoparticles and their long term aging characteristics are reported. High Resolution Transmission Electron Microscopy and UV visible spectroscopy techniques are used to observe the variation in size, structure and oxidation state as a function of time. The morphology variation and the hierarchical assembly of nanostructures are imputed to the inherent structural aspects of cerium oxide. This communication also emphasizes the need for long term aging studies of nanomaterials in various solvents for multiple functionalities.
