A fibrillar, polymeric intermediate (Cd2Se)n was isolated from the synthesis of CdSe nanorods, which suggests that the reactants themselves can template anisotropic growth. It is shown that high monomer concentration is the principal factor favouring this reaction pathway. The intermediate is distinct from crystalline semiconductor or small clusters and is surprisingly temperature-stable below 250 °C.
一种纤维状、聚合的中间产物(Cd2Se)n 从 CdSe 纳米棒的合成中被分离出来,这表明反应物本身可以模板各向异性生长。研究表明,高单体浓度是有利于这种反应途径的主要因素。该中间产物与结晶半导体或小团簇不同,在 250°C 以下具有惊人的温度稳定性。
