Studies on the control of ZnO nanostructures by wet chemical method and plausible mechanism

Studies on the control of ZnO nanostructures by wet chemical method and plausible mechanism

This research article provides a pathway of controlled growth of ZnO nano-rods, -flowers, -needles or -tubes without external chemical catalysis, via a simple wet chemical method by control of synthesis temperature. Morphological effects on structural and optical properties are studied by Ultraviole...
