摘要：

ZnO nanorods with hexagonal structures were synthesized by the hydrothermal method at different conditions. Their room-temperature emission spectra and fluorescent dynamics were studied. The ultraviolet emissions of excitons (3.2 eV) and visible emissions (2.0 eV) from deep levels (DLs) of defects were observed. The results demonstrate that preparation condition pH influences the intensity ratio of the exciton emissions and DLs, as well as the decay time constant of DLs emissions.
