摘　　要：以三氯化锑为锑源,水—乙二胺混合液为溶剂,在室温下合成出形貌、晶型可控的三氧化二锑纳米材料.XRD、TEM结果表明,溶剂的组成对目标产物的形貌和晶型的调控起着关键作用.乙二胺为溶剂,可得到立方相三氧化二锑纳米颗粒,水含量为25%时,得到立方—正交混合相三氧化二锑纳米颗粒;当水的含量提高到75%时,得到纯正交相三氧化二锑亚微米棒,其直径约为60-110 nm范围内,长度在500-700 nm米范围内.Using SbCl3 as the source of Sb2O3,water-ethylenediamine as solvents,Sb2O3 nanomaterials with controllable phase and morphology were prepared at room temperature.The results of X-ray diffraction（XRD） and transmission electron microscope（TEM） show that the component of solvent plays an important role in the formation of different morphology and phase.When en was used as solvent,cubic phase Sb2O3 nanoparticles could be obtained.When the content of water was 25 %,cubic-orthorhombic phase Sb2O3 nanopartocles could be generated.When the content of water increased to 75 %,orthorhombic phase Sb2O3 nanorods（the diameter and length is 60-110 nm and 500-700 nm） can be obtained.
