Organic solvent-induced controllable crystallization of the inorganic salt Na3[Au(SO3)2] into ultralong nanobelts and hierarchical microstructures of nanowires

The present paper reports an organic solvent-induced controllable crystallization of a water-soluble inorganic salt Na(3)[Au(SO(3))(2)] into ultralong nanobelts and hierarchical microstructures of one-dimensional (1D) nanowires. It was found that the morphology of the resulting crystals can be fine tuned by simply varying the experimental parameters, such as the ratios of water to organic solvent and gold salt to organic solvent, as well as the type of organic solvent.
