这封信描述了单分散银纳米立方体的最快途径。通过向常规的多元醇合成中添加微量的硫化钠（Na 2S）或硫氢化钠（NaHS），反应时间从16-26 h显著缩短至38 min。仅通过调节反应时间，以相对大的规模快速且常规地制备边长为25-45 nm的单分散银纳米立方体。这些小的纳米立方体是非常感兴趣的生物医学应用的方式产生的金纳米笼与等离子体共振峰可调的近红外区域通过电流置换反应。(c)2006 Elsevier B. V.保留所有权利。
This Letter describes the fastest route to monodispersed silver nanocubes. By adding a trace amount of sodium sulfide (Na2S) or sodium hydrosulfide (NaHS) to the conventional polyol synthesis, the reaction time was significantly shortened from 16-26 h to 38 min. By merely adjusting the reaction time, monodispersed silver nanocubes of 25-45 nm in edge length were rapidly and routinely produced on relatively large scales. These small nanocubes are of great interest for biomedical applications by way of generating gold nanocages with plasmon resonance peaks tunable to the near-infrared region through a galvanic replacement reaction.
