摘要
本文采用真空饱和蒸汽反应法在相对较低的温度下制备了一系列一维纳米结构的金属有机配合物Ag(TCNQ)。用多晶XRD谱表征了样品的成份和晶体结构 ,通过SEM观察到了不同生长阶段的形貌。纳米晶须的生长分别经历了溶解、结晶和单向生长三个阶段。在此基础上 。
A series of one dimensional nanostructured organometallic complex,Ag(TCNQ),were prepared at a fairly low temperature using vacuum saturated vapor reaction.The composition and crystal structure of the obtained nanostructure were characterized by powder X ray diffraction (XRD).Scanning electron microscopy (SEM) were employed to monitor the microstructure in the growth processes,and its images showed that the formation of the Ag(TCNQ) nanocrystal whiskers includes three steps,i.e.co melting,crystallization and directional growth.The growth mechanism was further explained with the Vapor Liquid Solid (VLS) model.
