纳米粒子的合成不仅因为其基本的科学兴趣，而且也因为许多技术应用而受到广泛关注，[1]具有可控粒度的单分散纳米粒子（标准偏差σ 5%）至关重要，因为这些纳米粒子的电学，光学和磁性特性强烈依赖于它们的尺寸。[2，3]最近，已经开发了几种胶体化学合成方法来生产各种材料的单分散纳米颗粒。在经典的LaMer机制中，来自过饱和溶液的成核的短暂爆发之后是颗粒的缓慢生长，而没有任何显著的额外成核，从而实现成核和生长的完全分离。[4]各种类似的程序已被用于合成几乎单分散的CdSe纳米颗粒，[5]相关的II-VI族化合物。
The synthesis of nanoparticles has been intensively pursued not only for their fundamental scientific interest but also for many technological applications,[1] monodisperse nanoparticles (standard deviations σ 5%) with controlled particle sizes are of key importance because the electrical, optical, and magnetic properties of these nanoparticles depend strongly on their size.[2, 3]Recently, several colloidal chemical synthetic procedures have been developed to produce monodisperse nanoparticles of various materials. In the classical LaMer mechanism, a short burst of nucleation from a supersaturated solution is followed by the slow growth of particles without any significant additional nucleation, thereby achieving a complete separation of nucleation and growth.[4] Various similar procedures have been employed to synthesize almost monodisperse nanoparticles of CdSe,[5] related II–VI semiconduc-
