Abstract
Zinc oxide (ZnO) particles with extraordinary morphology and structure were observed after hydrothermal growth of the precursors in lyotropic liquid crystal (LLC) phase composed of discotic sunset yellow (SSY) molecules, sodium ions, and water. When the ZnO was grown in the conventional solution composed of zinc acetate (ZA) and hexamethylenetetramine (HMT), typical rodlike particles with hexagonal cross-section were observed. On the other hand, when the ZnO was grown in the nematic phase of the SSY, the lateral growth of the ZnO became prominent, forming discotic and donut-like particles. The lateral growth of the ZnO is thought to be induced by adsorption of the SSY and sodium ions on the polar surface of the ZnO nanorods (NRs). The morphologies and structure of the ZnO particles were experimentally analyzed, and a plausible growth model was suggested.
期刊介绍：
The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
