摘　　要：室温下,在含有表面活性剂TX-100的溶液中,利用低能超声搅拌制备得到星状Sb2O3纳米颗粒,用透射电子显微镜(TEM),高分辨透射电子显微镜(HRTEM),X-射线衍射仪(XRD),扫描电子显微镜(SEM),热分析仪(TG/DTA)对样品形貌和组成进行分析,并探讨了星状Sb2O3纳米颗粒的形成机理。制备方法简单、省时并有望用于其它纳米颗粒的制备。Star-like Sb203 nanoparticles was fabricated with low-power ultrasound agitation and the assistance of surfactant TX-100 in aqueous system at room temperature. The structure and morphology of as-synthesized sample were characterized by transmissii0n electron microscopy （TEM）, and high-resolution transmission electronmicroscopy （HRTEM）, X-ray diffraction （XRD）, scanning electron microscopy （SEM） and thermogravimetry-differential thermal analysis （TG/DTA）. Finally, the possible formation mechanism of the novel structures was proposed. The method introduced is simple, time-saving, and promising for synthesis of other nanosize materials.
