Tube-structured ZnO needles were successfully synthesized hydrothermally, using H2O2 as the solvent, Zn (NO3)2o6H2O and NaOH as the starting materials and C19H42BrN as the additive. The samples were characterized by scanning electron microscopy, X-ray diffraction and room temperature photoluminescence measurements. The as-synthesized ZnO needle possesses a tube structure coiled by multilayer along the [0001] direction and a wurtzite structure. The intensity of the (0002) diffraction peak is obviously lower than the (10?0) and (10?1) peaks. Photoluminescence results reveal that the UV emission is restrained as hydrothermal temperature increases, and that the concentration of H2O2 has no influence on the photoluminesence when the concentration of H2O2 is higher than 10%.
