Morphology-tuned growth of ZnO microstructures

摘要: Abstract Morphology-tuned ZnO microcrystals can be prepared by oxidizing zinc metal substrates in aqueous solution using hydrothermal technique. Some typical growth morphologies such as nanorod superstructures, arrays, microspheres, hierarchical nanostructures, and split crystals have been chemically fabricated. These microscopic shapes finely controlled selecting Zn(NO3)2 concentration solvent. A conceptual model was proposed to explain the formation of as-prepared structures proper kinetic environments. This one-step, wet-chemical approach is controllable reproducible, which conveniently transferred industrial applications.
