| 摘 要： | 在表面活性剂PEG-400存在的条件下,以醋酸铜和硫代乙酰胺为原料,利用低热固相化学反应,一步制备出分散均匀的硫化铜纳米棒.X射线粉末衍射和能量散射X射线能谱分析证明,产物为纯六角相的硫化铜.透射电镜和扫描电镜形貌分析表明,产物为棒状,直径为80～100nm,长度为200～500nm.紫外-可见光谱和光致发光光谱表明,硫化铜纳米棒的紫外和荧光最大吸收和发射波长与常规硫化铜相比均发生了明显的蓝移,表明所制备的硫化铜纳米棒具有良好的光学性质.

| Abstract: | Well-dispersed copper acetamide sulfide nanorods were prepared by means of the solid-state reaction of copper acetate and thioacetamide in the presence of surfactant PEG-400 at a low heating temperature. The powder X-ray diffraction pattern and EDX indicated that the product was pure hexagonal phase copper sulfide nanorods. The morphology of the nanorods was characterized by transmission electron microscopy(TEM) and scanning electron microscopy(SEM). The diameter and length of CuS nanorods obtained are 80-100 nm and 200-500 nm, respectively. And the maximum peak positions of absorption spectrum and excited spectrum of CuS nanorods were observed to shift towards higher wave number compared with those of the bulk CuS. The results clearly show the fine optical properties of CuS nanorods. |
