Synthesis of ZnO nanorods by wet-chemical method at low temperature

At low temperature the ZnO nanorods were synthesized by the refluxing method in the presence of DBS (Dodecyl benzene sulfonic acid sodiumsalt). The samples were characterized by SEM, optics microscopy and XRD techniques. The results showed that the ZnO nanorods were 100 nm in diameter and 1 μm in length. It was found that the parameters including the temperature, the content of surfactant, the ultrasonic and refluxing time had important influence on the formation of the ZnO nanorods. Compared with other methods, that used ultrasonic and low temperature conditions were key to form uniform ZnO nanorods with smaller diameter.
