Abstract： Taking zinc nitrate hexahydrate as zinc sources, ZnO nano-spheres constituted by the oriented aggregation of nano-particles were synthesized by hydrothermal method. ZnO spheres with various diameters were obtained by regulating volume ratios of triethanolamine to H2O. The structure and morphology of the obtained samples were characterized by XRD, IR, SEM and UV -Vis. The results show that the samples are hexagonal wurtzite ZnO. The possible growth mechanism of the nano-spheres is that ZnO nano-crystalline particles are synthesized from zinc nitrate hydrolyzed in triethanolamine solution and then directionally aggregated.
Keywords： ZnO nano-sphere; hydrothermal method; optical absorption; growth mechanism
