摘　　要：运用水热法大量制备出了高长径比的硫化锑(Sb2S3)纳米带。十六烷基三甲基溴化铵(CTAB)作为形貌控制剂在纳米带的形成过程中起了至关重要的作用,运用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和高分辨透射电镜(HRTEM)等对所得产物进行了系统的表征,结果表明制备出的Sb2S3纳米带是沿[001]晶面方向生长的,带的宽度在1μm以内,长度可达几十个微米。对Sb2S3纳米带的生长机理和光学性质进行了初步的讨论和研究。Single-crystalline Sb2S3 nanoribbons have been successfully prepared by a simple hydrothermal method.It was found that CTAB plays a key role in the formation of the Sb2S3nanoribbons.The morphology and structure of the obtained nanoribbons were characterized by XRD,SEM,TEM,and HRTEM in detail,indicating that the prepared Sb2S3nanoribbons grows along the[001]crystal face.The widths of these nanoribbons are around 1μm and lengths of tens of micrometers.The growth mechanism and optical properties of the obtained nanostructures were also discussed and measured.
