A solution chemistry approach for the selective formation of ultralong nanowire bundles of crystalline Cd(OH)(2) on substrates
The controlled precipitation of a supersaturated Cd2+ solution is used to selectively deposit Cd(OH)(2) nanowire bundles on a substrate. As schematically depicted in the figure, when the Cd2+ ionic product exceeds the solubility product, heterogeneous and homogeneous nucleation occur independently on the substrate and in the solution to give nanowire bundles and hexagonal plates, respectively.
