SnO₂ nanorods were deposited on the Si substrates in an aqueous solution containing both SnCl₄ and CO(NH₂)₂. It is found that different self-assembled patterns of SnO₂ nanorods can be obtained by changing the deposition conditions such as the molar ratio of CO(NH₂)₂ to SnCl₄ and the pretreatment of the substrate. Scattered SnO₂ nanorods, for example, can be changed into flower-like patterns when the molar ratio of CO(NH₂)₂ to SnCl₄ is raised, and well-aligned nanorod arrays can be formed when the pretreatment of the snbstrate is changed. In addition, some interesting patterns, e.g. tree-like patterns, can also be observed.
