在空气中成功地合成了由超细纳米线组成的KxWO_3纳米片。详细的电子显微镜和X射线衍射研究表明，纳米薄片是由有序纳米线自组装而成的，这些纳米线在bar0}(H)面上暴露出{01(1)。片层的形貌与生长条件密切相关，包括温度、时间等。提出了一种基于相邻纳米线定向附着形成纳米片层的可能机制。我们的结果揭示了自组装KxWO_3纳米线的界面特性，并为未来各种电气和光学应用的相关二维结构的设计提供了指导。
The KxWO3 nanosheets consisting of superfine nanowires were successfully synthesized in ambient air. The detailed electron microscopy and X-ray diffraction investigations imply that the nanosheets were obtained by self-assembly of the ordered nanowires with exposed {01 (1) over bar0}(H) facets. The sheet morphology is closely related with the growth conditions including temperature and time, etc. A possible mechanism based on the oriented attachment of neighboring nanowires for the formation of nanosheets is proposed. Our results shed light on the interfacial characteristics of self-assembled KxWO3 nanowires and can serve as guidance to the future design of relevant two-dimensional structures for various electrical and optical applications.
