Abstract
Well-aligned ZnO nanorod arrays were obtained at 90 ℃,using zinc foil as the substrate and zinc nitrate and ammonia as source materials,in the absence of any surfactants by hydrothermal method.As-synthesized ZnO nanorod arrays are from 500 to 800 nm in the length,and are about 100 nm in the diameter.The results show that the top of the nanorod is hexagonal and owns the wurtzite structure.Also,the effect of experimental parameters on the morphology and structure of as-products are studied systematically.
