Abstract

We report the preparation of CdS nanorods using a thiosemicarbazide complex of cadmium [Cd(NH2CSNHNH2)2Cl2]. The precursor was decomposed in tri-n-octylphosphine oxide (TOPO) at 280 degrees C to give TOPO capped CdS nanoparticles; nano-dimensional rods of the material are clearly visible in transmission electron microscopy (TEM); the particles have been further characterised by X-ray diffraction (XRD) and selected area electron diffraction (SAED) and optical measurements.

摘要

我们报道了使用镉的硫代氨基脲配合物[Cd(NH2CSNHNH2)2Cl2]制备硫化镉纳米棒的方法。前驱体在280℃下于三正辛基氧化膦（TOPO）中分解，得到TOPO包覆的硫化镉纳米颗粒；在透射电子显微镜（TEM）中可以清晰地看到该材料的纳米尺寸棒；通过X射线衍射（XRD）、选区电子衍射（SAED）和光学测量对颗粒进行了进一步表征。
