Silver nanowires were successfully prepared by one-step growth method in aqueous environment. The suitable pH value is a key factor for the successful preparation of silver nanowires. The concentration of silver nitrate precursors also affects the yield of silver nanowire. We studied the growth mechanism of silver nanowires in detail. This is a classic Ostwald ripening process. The final silver nanowires are face-centered-cubic (FCC) phase. The morphologic parameters of the silver nanowires were observed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Its size is about 7 μ m long and about 45 nanometers in diameter. This experiment provides an effective method for the preparation of silver nanowires in aqueous environment. It has important potential applications in biological detection and physical devices.

在水环境中一步一步生长银纳米线的方法

通过在水环境中一步生长法成功制备了银纳米线。合适的pH值是成功制备银纳米线的关键因素。硝酸银前体的浓度也影响银纳米线的产率。我们详细研究了银纳米线的生长机理。这是经典的Ostwald成熟过程。最终的银纳米线为面心立方（FCC）相。通过透射电子显微镜（TEM）和扫描电子显微镜（SEM）观察银纳米线的形貌参数。它的大小约7微米长，直径约45纳米。该实验提供了在水性环境中制备银纳米线的有效方法。它在生物检测和物理设备中具有重要的潜在应用。
