Abstract

An efficient hydrothermal method is presented to synthesize ZnO nanostructures. We investigated the effects of reaction conditions by adjusting the amounts of NaOH, growth temperature, surfactant, annealing to control the morphologies of ZnO nanostructures. Critical amount of NaOH in our reaction system has great influence on the formation of ZnO nanorods. The diameter of ZnO nanocrystals decreased with growth temperature and morphology changed from nanorods to flowers when PEG400 was added to the solution.
