Several tests were conducted using X-ray fluorescence, particle size analyzer, scanning electron microscopy, X-ray diffraction and transmission electron microscopy. The diameter of ZnO nanorods varies from 43nm to 200nm which can be seen from SEM images and its length varies from 160nm to 1000nm. These nanopowders are rod shape as can be seen from TEM images. The XRD data shows a sharp peak at 36.21o which indicates a good crystal growth and agrees well with JCPDS card no. 36-1451. Effects of electrical current variations of 20, 25 and 30 Amperesto the size of ZnO nanorods are also indicated from aspect ratio of about 8.27, 8.44 and 8.81 respectively. The ultraviolet absorption test results show that the ZnO nanorods can absorb UV with the absorbance ranges of300nm and 340nm wave lengths as well as the peak is at the wave length of 311nm. Photoluminescence test confirmsthat the ZnO spectra are in blue emission with the optimum excitation wavelength of 240nm. It can be concluded that this method is well proven in synthesizing high purity compound, UV-block ability and good luminescence ZnO nanorods.}, keywords = {ZnO,Zinc oxide,thermal plasma,nanopowders,nanorods}, url = {https://scientiairanica.sharif.edu/article_3470.html}, eprint = {https://scientiairanica.sharif.edu/article_3470_f641763bf3698c2ece276ef1efd6f5b2.pdf} }
