    Study on synthesis and characterization of ZnO nanorods are reported. Low power DC thermal plasma was successfully employed to fabricate these ZnO nanorods. Several testing were conducted including X-ray fluorescence (XRF), particle size analyzer (PSA), scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The diameter of resulted ZnO nanorods varies from 43 nm to 200 nm which can be seen from SEM images and its length varies from 160 nm to 1000 nm. These nanopowders are in rod shape as can be seen clearly from TEM images. The XRD data shows a sharp peak at 36.21o which indicates a good crystal growth and agrees well with the standard data (JCPDS card no. 36-1451). Effects of electrical current variations of 20, 25 and 30 Ampereere to the size of ZnO nanorods are also indicated from aspect ratio of about 8.27, 8.44 and 8.81 respectively. The ultraviolet (UV) absorption test results show that the ZnO nanorods can absorb UV with the absorbance ranges are about 300 nm and 340 nm wave lengths as well as the peak is at the wave length of 311 nm. Photoluminescence test confirm that the ZnO spectra are in blue emission with the optimum excitation wavelength of 240 nm. It can be concluded that this method is well proven in synthesizing ZnO nanorods having perfect single crystalline size, high purity compound, UV-block ability and good luminescence characteristics by spending low electrical power.
