Preparation of ZnO Nanorods via Surfactant Assisted Hydrothermal Synthesis
表面活性剂辅助水热合成氧化锌纳米棒

By using Zn4CO3(OH)6·H2O as the precursor, cetyltrimethyl ammonium bromide (CTAB) as the surfactant, ZnO nanorods with several nanometer diameters were synthesized. The product was characterized by means of X-ray powder diffraction (XRD), transmission electron microscope (TEM) and selected area electron diffraction (SAED). Its room-temperature photoluminescence properties were also studied. The results show that the as-prepared products have high crystallinity and grow along the 001 direction, combining with good near UV emission properties. The mechanism for the ZnO nanorod growth was also discussed.
