该通信报告的高度均匀的KNbO 3纳米线的生长表现出约60 nm的窄直径分布和长-宽比高达100。纳米线是通过水热路线制备的，这使得简单的克级生产成为可能。通过改变温度-压力条件和起始混合物的组成，对合成的纳米线的形态和化学特征进行了系统的研究。结果表明，高度均匀的单晶纳米线形成在一个狭窄的窗口内的三元相图的KOH-Nb 2 O 5-H2O。
This communication reports on the growth of highly uniform KNbO3nanowires exhibiting a narrow diameter distribution around 60 nm and a length-to-width ratio up to 100. The nanowires were prepared by a hydrothermal route, which enables simple, gram-scale production. A systematic study of the synthesized nanowires in terms of the morphological and chemical characteristics was carried out by varying the temperature−pressure conditions and the composition of the starting mixture. The results indicate that highly uniform single-crystalline nanowires form within a narrow window of the ternary phase diagram of KOH−Nb2O5−H2O.
