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。
SrF2 nanosheet self-assembled microspheres were prepared by a simple sonochemical method. The synthesized product was characterized and analyzed by powder X-ray diffractometry, field emission scanning electron microscopy and transmission electron microscopy. The results showed that these microspheres were composed of regular and ordered nanosheets. These nanosheets perpendicularly connected to each other and assembled into microspheres. The study also found that the concentration of reactants, complexing agent and pH value of the product morphology and size play an important role.
