摘要/Abstract

摘要：

采用水热法合成高长径比的碲纳米线, 用搅拌辅助界面组装将其取向排列在石英表面, 同时考察了基片内外侧、溶剂、搅拌转数和溶液浓度等条件对组装形貌的影响; 以取向排列的碲纳米线为模板, 利用化学转化法原位制备了Pt, Pd和Ag₂Te的纳米线二维阵列, 为有序界面组装提供了新方法.

关键词: 界面组装, 取向排列, 搅拌, 碲纳米线

Abstract:

We investigated the ordered assembly of Te nanowires under the assistance of agitation and prepared several nanowires arrays through in situ chemical reaction of the assembled Te nanowires. The Te nanowires with long aspect ratio were synthesized through hydrothermal method and then were aligned on the substrate of quartz by agitation-assisted assembly. The influences of the sides of the substrate, solvent, stirring rate and concentration on the morphology of the assembled nanowires were studied. Using the orientated Te nanowires as templates, the arrays of Pt, Pd and Ag₂Te nanowires were fabricated by in situ chemical conversion. Due to the distinct properties of the above nanowires, the prepared arrays would be of great potential in the fields of sensor and photoelectronic device. This study indicates the capability of the agitation-assisted assembly in the fabrication of nanowires array, offering a new approach to obtain two-dimension ordered structure.

Key words: Surface assembly, Nanowires alignment, Agitation, Te nanowires
