Influence of Growth Time and Temperature on the Morphology of ZnO Nanorods via Hydrothermal

This research investigates the effect of temperature and growth duration on the morphology of ZnO. ZnO nanostructure can be synthesized via hydrothermal method using Zinc Acetate and hexamethylenetetramine (HMT) as precursor and glass slide as a substrate. The temperature and growth time vary from 50-95 degrees C and 50-100 minutes, respectively. The substrates with ZnO nanostructures are annealed at different temperatures which are 200 degrees C and 500 degrees C. The result indicates that different temperature and growth time produces different morphologies in size. Thus, the morphology of ZnO nanostructure affects by the parameters such as temperature and growth time via hydrothermal grown.
