Bi2Te3纳米结构的制备、磁性掺杂和结构表征

摘要

通过液相法制备Bi2Te3纳米管,设计并优化了Co离子的掺磁方案.通过扫描电镜、透射电镜、X射线衍射、红外光谱和能量色散 X射线光谱对制备的样品进行了结构表征.实验结果表明,液相法可制备出晶相良好的Bi2Te3纳米管、Co离子均匀掺杂的Bi2Te3纳米结构样品.%The Bi2Te3nanotubes were prepared by liquid phase method,the Co ions doped magnetic solution was designed and optimized.The structure characterization of the samples were analyzed by scanning electron microscopy,transmission electron mi-croscopy,X-ray diffraction,infrared spectrum and energy dispersive X-ray spectrum.The experimental results show that the liquid phase method can produce Bi2Te3nanotubes with good crystal phase and Bi2Te3nanostructure with uniform Co ions doped.
