Disordered Structure

The morphology of SnO2nanoarrays prepared on indium tin oxide (ITO) substrates by hydrothermal method can be controlled through using different surfactants. The surfactants play an important role in influencing the morphology and size of SnO2nanoarrays. The rod-like nano-arrays prepared by using cationic surfactant, disordered structure randomly assembled by nanoparticle obtained by using anionic surfactant, the flower-like nanoarrays synthesized by using nonionic surfactant. Furthermore, the effect of the amount of nonionic surfactant-polyvinyl pyrrolidone(PVP) on the morphology and size of flower-like SnO2nanoarrays has systematically been investigated.
