Highly uniform CdTe nanowires with a very high aspect ratio of approximately 1000 and an average diameter of 12 nm can be conveniently synthesized using ultrathin Te nanowires as templates via a low-temperature hydrothermal process. Several other interesting CdTe nanostructures, including tadpolelike, chainlike, and branched nanostructures, can also be fabricated by adjusting precursor concentrations and reaction temperature. The formation mechanism of uniform CdTe nanowires using highly reactive ultrathin Te nanowires as template has been discussed. The synthesized uniform CdTe nanowires can be well-dispersed in water or ethanol, and they may find potential applications in the fields of photovoltaics, biological sensors, and nanoscale electronics. The present templating method can also be extended to synthesize other one-dimensional telluride nanostructures such as PbTe nanowires with uniform diameter and high aspect ratios.
通过低温水热法，以超薄碲纳米线为模板，可以方便地合成具有约1000的非常高的纵横比和12nm平均直径的高度均匀的碲化镉纳米线。通过调节前驱体浓度和反应温度，还可以制备其他几种有趣的碲化镉纳米结构，包括蝌蚪状、链状和分支状纳米结构。已经讨论了以高反应性超薄碲纳米线为模板制备均匀碲化镉纳米线的形成机理。合成的均匀碲化镉纳米线可以很好地分散在水或乙醇中，并且它们可能在光伏、生物传感器和纳米级电子学领域找到潜在应用。目前的模板法也可以扩展到合成其他一维碲化物纳米结构，如具有均匀直径和高纵横比的碲化铅纳米线。
