以Ni、S和FeCl 2·4 H2O为原料，采用溶剂热法在乙二胺溶剂中成功合成了形貌均匀的单晶Fe掺杂NiS三元纳米棒。采用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、X射线能谱（EDS）和透射电子显微镜（TEM）对产物的物相、形貌、成分和显微结构进行了表征。结果表明，Ni 1 −xFexS纳米棒结晶良好，最高Fe掺杂浓度为17.51%。Fe ~（2+）离子的加入促进了纳米棒的一维生长，增大了纳米棒的带隙。
Single-crystalline Fe-doped NiS ternary nanorods with uniform morphology have been successfully synthesized in ethylenediamine solvent by a solvothermal technique using Ni, S and FeCl2⋅4H2O as starting materials. The phase, morphology, compositions and microstructure of the products have been characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The results show that the Ni1−xFexS nanorods are well crystallized and the highest Fe doping concentrationxis about 17.51%. The addition of Fe2+ions can facilitate the one-dimensional growth and enlarge the band gaps of the nanorods.
