CdS nanorods were synthesized on a large scale by thermolyzing a single-source precursor, (Me(4)N)(4)[S(4)Cd(10)(SPh)(16)], in a single surfactant system. Transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and x-ray powder diffraction (XRD) have been used to characterize the morphology and crystal structure of the sample. The TEM images show that the CdS nanorods are uniform with an aspect ratio of about 9:1. The XRD result demonstrates that the nanorods are in a wurtzite structure. The nanorods exhibit quantum size effects from the optical absorption spectrum. The influence of reaction conditions on the growth of CdS nanorods demonstrates that high precursor concentration and high reaction temperature (>190 °C) are favorable for the formation of CdS nanorods.
通过在单一表面活性剂体系中热解单源前驱体（Me(4)N)(4)[S(4)Cd(10)(SPh)(16)]，大规模合成了硫化镉纳米棒。采用透射电子显微镜（TEM）、高分辨率透射电子显微镜（HRTEM）和X射线粉末衍射（XRD）对样品的形貌和晶体结构进行了表征。TEM图像显示，硫化镉纳米棒均匀，长径比约为9:1。XRD结果表明，纳米棒为纤锌矿结构。纳米棒从光吸收光谱中表现出量子尺寸效应。反应条件对硫化镉纳米棒生长的影响表明，高前驱体浓度和高反应温度（>190°C）有利于硫化镉纳米棒的形成。
