Abstract
ZnO microrods were prepared on indium tin oxide-coated glass substrate by a hydrothermal method. ZnO microrods were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscope, energy-dispersive X-ray spectrometer, photoluminescence, and UV–visible spectrum. ZnO microrods were pure wurtzite phase. The formation mechanism was discussed, especially emphasizing the formation mechanism of ZnO clusters and twinned ZnO structures. Green and orange emissions in photoluminescence were attributed to O vacancies and O interstitials, respectively.
