Well-crystallized zinc oxide nanorods have been fabricated by single step solid-state reaction using zinc acetate and sodium hydroxide, at room temperature. The sodium lauryl sulfate (SLS) stabilized zinc oxide nanorods were characterized by using X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and photoluminescence spectroscopy. The X-ray diffraction revealed the wurtzite structure of zinc oxide. The size estimation by XRD and TEM confirmed that the ZnO nanorods are made of single crystals. The growth of zinc oxide crystals into rod shape was found to be closely related to its hexagonal nature. The mass ratio of SLS:ZnO in the nanorods was found to be 1:10 based on the thermogravimetric analysis. Blue shift of photoluminescence emission was noticed in the ZnO nanorods when compared to that of ZnO bulk. FT-IR analysis confirmed the binding of SLS with ZnO nanorods. Apart from ease of preparation, this method has the advantage of eco-friendliness since the solvent and other harmful chemicals were eliminated in the synthesis protocol.
通过在室温下使用醋酸锌和氢氧化钠进行单步固态反应，制备出了结晶良好的氧化锌纳米棒。采用X射线衍射、傅里叶变换红外光谱、透射电子显微镜和光致发光光谱对月桂基硫酸钠（SLS）稳定的氧化锌纳米棒进行了表征。X射线衍射显示了氧化锌的纤锌矿结构。通过XRD和TEM进行的尺寸估计证实，ZnO纳米棒由单晶制成。发现氧化锌晶体生长成棒状与其六方性质密切相关。基于热重分析，发现纳米棒中SLS与ZnO的质量比为1:10。与块状ZnO相比，ZnO纳米棒的光致发光发射出现蓝移。FT-IR分析证实了SLS与ZnO纳米棒的结合。除了制备简便外，该方法还具有环保的优点，因为在合成过程中消除了溶剂和其他有害化学物质。
