Synthesis and Raman Behaviors of ZnO Nanorods by a Surfactant-Free and Low-Temperature Process

Abstract:

ZnO nanorods were successfully synthesized using ZnCl₂ and NaOH as the starting materials without surfactants, template supporting and structure-directing solvent at low temperatures (20 °C 90 °C). X-ray powder diffraction (XRD) and transmission electron microscopy (TEM) were used to analyze the crystal structure and surface morphology. Analysis of XRD patterns showed that ZnO clusters are single hexagonal phases of wurtzite structure with no other impurities. Also, TEM images revealed that the size of a single ZnO nanorod was between 32 and 60 nm in diameter and between 470 and 740 nm in length. Furthermore, the ZnO nanorods exhibited significant Raman spectrum optical properties suggesting that they have potential for opto-electronic application.
