水热法制备F/Mn共掺杂SnO2纳米粒子

Synthesis and characterization of F/Mn Co-doped SnO2 nanoparticles by hydrothermal method

摘要:

本文采用水热法制备了具有金红石结构的F-Mn共掺杂SnO2纳米粒子，研究了碱源、pH值、掺杂剂、表面活性剂、煅烧温度对F/Mn共掺杂SnO纳米粒子晶相、微观形貌、分散性和光学性能的影响。采用X射线衍射（XRD）、扫描电镜（SEM）和紫外/可见/近红外分光光度计对F-Mn共掺杂SnO2纳米粒子进行了表征。结果表明，该方法可以获得较高的结晶度、较小的粒径和分散良好的F-Mn共掺杂SnO2纳米粒子。F-Mn共掺杂SnO2涂层具有较好采光的同时有较高的近红外屏蔽性能，其中可见光透过率约为90%，近红外阻隔率约为93%左右。

Abstract:

F-Mn Co-doped SnO₂ nanoparticles with rutile structure have been successfully synthesized by hydrothermal method at low temperature. In the hydrothermal method, surfactant plays an important dispersion role. The nanostructures have been characterized by means of XRD. XRD results show that the nanostructures are crystalline with rutile structure. The morphology of as-prepared samples was characterized by scanning electron microscopy (SEM). Effects of pH, dopant, surfactant and alkali source on morphology, dispersion, Crystal crystallinity and nanoparticles diameter are discussed.
