Abstract

High quality CdS nanorods are synthesized reproducibly with cadmium acetate and sulfur as precursors in trioctylphosphine solution. The morphology, crystalline form and phase composition of CdS nanorods are characterized by transmission electron microscopy (TEM), high-resolution TEM and X-ray diffraction (XRD). CdS nanorods obtained are uniform with an aspect ratio of about 5:1 and in a wurtzite structure. The influence of reaction conditions on the growth of CdS nanorods demonstrates that low precursor concentration and high reaction temperature (260 degrees C) are favorable for the formation of uniform CdS nanorods with 85.3% of product yield.

摘要

以醋酸镉和硫为前驱体，在三辛基膦溶液中可重复合成高质量的硫化镉纳米棒。通过透射电子显微镜（TEM）、高分辨率TEM和X射线衍射（XRD）对硫化镉纳米棒的形貌、晶型和相组成进行了表征。所制备的硫化镉纳米棒均匀，长径比约为5:1，呈纤锌矿结构。反应条件对硫化镉纳米棒生长的影响表明，前驱体浓度低和反应温度高（260℃）有利于形成均匀的硫化镉纳米棒，产物产率为85.3%。
