Single-crystal CdTe nanorods with diameters of 50-100 nm were synthesized under a surfactant-assisted hydrothermal condition. The experimental results indicated that with a temporal dependence the morphologies of CdTe nanocrystallites changed from nanoparticles to smooth surface nanorods. The crystal structure, morphology and optical properties of the products were investigated by x-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and fluorescence spectrophotometer. Furthermore, the formation mechanisms of the nanorods were investigated and discussed on the basis of the experimental results.
在表面活性剂辅助水热条件下合成了直径为50 - 100纳米的单晶碲化镉纳米棒。实验结果表明，随着时间的推移，碲化镉纳米微晶的形态从纳米颗粒变为表面光滑的纳米棒。通过X射线衍射（XRD）、透射电子显微镜（TEM）、高分辨率透射电子显微镜（HRTEM）、扫描电子显微镜（SEM）和荧光分光光度计对产物的晶体结构、形态和光学性质进行了研究。此外，根据实验结果对纳米棒的形成机制进行了研究和讨论。
