采用单源前驱体Bi（S2 CNEt 2）（3）在530 ℃下热解制备了单晶Bi 2S 3纳米管。X射线衍射（XRD）、拉曼光谱、能谱（EDS）分析表明，纳米管由纯的斜方晶系Bi 2S 3相组成。扫描电子显微镜（SEM）和透射电子显微镜（TEM）显示Bi 2S 3纳米管具有矩形或多边形开口端，横截面宽度为100-500 nm，长度可达几微米。纳米管从中心向两个或多个不同方向径向生长，形成稻草束状形态。高分辨透射电子显微镜（HR TEM）和选区电子衍射（SAED）表明，纳米管为单晶，沿沿着[001]方向生长。(c)2006爱思唯尔有限公司保留所有权利。
Single-crystalline Bi2S3 nanotubes have been prepared by pyrolyzing single-source precursor Bi(S2CNEt2)(3) at 530 degrees C. X-ray diffraction (XRD), Raman spectrum, energy-dispersive spectroscopy (EDS) demonstrate that the nanotubes are composed of pure orthorhombic phase Bi2S3. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that the Bi2S3 nanotubes have rectangular or polygonal open ends with cross-sectional width of 100-500 nm, and length up to several microns. The nanotubes grow radially from a center toward two or more different directions to form straw-bundle-like morphology. High-resolution (HR) TEM and selected-area electron diffraction (SAED) demonstrate that the nanotubes are single-crystalline and grow along the [001] direction. (c) 2006 Elsevier Ltd.
