Controllable Additive-Free Solvothermal Synthesis of Cadmium Sulfide Three Dimensional Assemblies
The potential application of nano-/microcrystals-based materials depends not just on the size, compositions and surface chemistry of the crystals, but also on their special morphologies and arrangements. Therefore, developing straightforward and controllable methods for self-assembly of nanostructures in 1 dimension and higher dimensions has attracted considerable attention. In this paper, cadmium sulfide 3 dimensional assemblies of nano-/microcrystals with controllable morphologies and arrangements were prepared through an efficient additive-free solvothermal process. The morphologies and arrangements of the 3 dimensional assemblies can be adjusted and controlled conveniently through the adjustment of the preparation conditions, such as the composition of the solvent, the ratio of reactants, the cadmium sources, and the pH values of the experiments. It presents a facile, efficient, and controllable method to prepare 3 dimensional architectures of nano-/micro-crystals with controlled morphologies and arrangements.
