| 摘 要： | 采用bottom-up制备纳米材料技术,在ITO导电玻璃上电化学恒电位沉积制备了一种由纳米线变异为纳米带,进而构成的“纳米花”形貌的热电材料。采用FE-SEM技术手段对纳米花形貌进行研究,探讨了热电纳米花材料的形成机理,模拟了纳米花形成过程。结果分析表明,纳米花是经过两个阶段形成的：首先是纳米线在热处理过程逐渐形成纳米带,然后,由纳米带收缩形成纳米花；热处理条件对纳米花的形成起到决定性的作用。

| Abstract: | Following the bottom-up technology, the flower-shaped nanomaterials consisted of nanobelts and nanowirs were fabricated on ITO-coated glass substrate by electrodeposition. The morphology of the as-prepared nano-flower was analized by FE-SEM. Moreover, the forming process was simulated. The results showed that the nano-flowers were fabricated through the two steps: first, nanowires formed gradually into nanobelts during the couse of thermal treatment; second, nanobelts contracted into nano-flowers. In addition, the conditions of thermal treatment played the determined role on the flower-shaped Bi2Te2.7Se0.3thermoelectric materials. |
