Template-free self-assembly of hierarchical ZnO structures from nanoscale building blocks

摘要: We study chemical bath deposition method for synthesizing large variety constructions of ZnO nanostructures. By varying reaction kinetics we control the shape, size and morphology to yield flower-like, rolling-pin-like, viscous-fingers-like antenna-like structures. In solution-based methods, factors responsible crystal growth are largely affected by slight changes in processes/conditions cause different hierarchical architectures when very low concentrations precursor material used. The ability grow morphologies just controlling solution parameters may open up new avenues provide systems natural behavior materials as well their novel applications.
