Purposes—To prepare ZnO nanoparticles with zinc acetate dihydrate and sodium hydroxide as raw materials,and to investigate the effect of the morphology of ZnO nanomaterials on their photoelectric performance.Methods—ZnO nanoparticles were synthesized with one-step hydrothermal method.The effects of the molar ratio of reactants,hydrothermal temperature and hydrothermal time on the morphology of ZnO nanomaterials were investigated through characterizing structure and morphology of the synthesized samples with...
