Thin, long gold/silver nanowires were grown on substrates in thin surfactant solution films. This growth process occurred exclusively in thinning aqueous films as the water evaporated, and elongated surfactant template structures were formed. The nanowire growth depended on the presence of a relatively high concentration of silver ions (typical Ag:Au mole ratio of 1:1). Tuning the pH value to about 5 in the growth solution was crucial for the nanowire growth. Further development of this process may lead to a simple wet chemical technique for the fabrication of relatively uniform arrays of metal nanowires on surfaces.
在薄的表面活性剂溶液薄膜中,在基底上生长出细而长的金/银纳米线。这种生长过程仅在水蒸发时稀化的水膜中发生,并形成拉长的表面活性剂模板结构。纳米线的生长取决于相对高浓度银离子的存在(典型的银:金摩尔比为1:1)。将生长溶液的pH值调节至约5对纳米线的生长至关重要。该工艺的进一步发展可能会导致一种简单的湿化学技术,用于在表面制备相对均匀的金属纳米线阵列。
