Characterization of nanostructures ZnO synthesized through hydrothermal method

ZnO nanostructures can be derived using a variety of techniques. Using hydrothermal synthesis, ZnO nanostructures can be produced easily on a large scale due to the low temperature involved. Among the factors that influence the crystallinity of ZnO nanostructures are types of alkaline solution, the...
