The characterization of various ZnO nanostructures using field-emission SEM

Zinc oxide (ZnO) is a unique material that has prompted a vast amount of research. Various morphologies and sizes of ZnO materials have led to a wide range of promising applications. Although research related to the applications of ZnO is progressing rapidly, it has been an enormous challenge to produce uniform ZnO materials. A unique synthesis method to produce ZnO materials with various morphologies has been studied and is presented in this paper. Field-emission scanning-electron microscopy has been utilized to characterize ZnO materials in this study to show how the synthesis conditions control the morphologies of ZnO
