采用熔盐法实现了硅酸镱（Yb 2SiO 5）纳米粒子和纳米棒的大规模合成。通过X射线衍射、透射电子显微镜（TEM）和高分辨透射电子显微镜（TEM）对合成产物进行了结构和形貌表征。结果表明，通过改变熔盐反应的反应物，可以很容易地控制Yb 2SiO 5产物的形貌.以NP-7.5为表面活性剂，可以得到高产率的单晶Yb 2SiO 5纳米棒。对Yb 2SiO 5纳米结构的形成机理进行了讨论.本文介绍的Yb 2SiO 5纳米结构的合成方法，为Yb 2SiO 5纳米结构作为环境阻隔涂层材料的应用奠定了基础。
Large-scale synthesis of ytterbium silicate (Yb 2 SiO 5 ) nanoparticles and nanorods has been realized by a facile molten-salt approach. The synthesized products were structurally and morphologically characterized by X-ray diffraction, transmission electron microscopy (TEM), and high-resolution TEM. Our results revealed that the morphologies of Yb 2 SiO 5 products can be readily controlled by a simple variation of the reactants used for the molten-salt reaction. Single-crystalline Yb 2 SiO 5 nanorods with a high yield can be obtained using NP-7.5 as a surfactant. The formation mechanism of Yb 2 SiO 5 nanostructures was also discussed. The method presented here for the synthesis of Yb 2 SiO 5 nanostructures may pave the way for their application as environmental barrier coating materials.
