【摘要】 通过简单的超声化学方法制备了SrF2纳米片自组装微球。合成的产物通过粉末X射线衍射仪、场发射扫描电子显微镜、透射电子显微镜进行了表征和分析,结果表明这些微球是由规则、有序的纳米片组成。而这些纳米片互相垂直连接组装成微球。研究还发现反应物的浓度,配位剂和pH值对产物的形貌和尺寸有着重要的作用。更多还原

【Abstract】 The SrF2 microspheres by the self-assembly of nanoplates are fabricated via a facile sonochemical route.The products were characterized by the X-ray diffraction(XRD),field emission scanning electron microscopy(FE-SEM),and transmission electron microscopy(TEM).The results showed that the microspheres with a hierarchical structure are composed of regularly ordered nanoplates.These nanoplates are connected with each other to form sphere with vertical orientation.The concentrations of the reactants,capping agent and pH value have important effects on the morphologies and sizes of the products.更多还原
