An easy shortcut synthesis of thermally stable, near-monodisperse Bi nanoparticles from BiCl(3) and Na[N(SiMe(3))(2)] is described. The diameters of the Bi nanoparticles are controlled in the range of 4-29 nm by varying the amounts of BiCl(3) and Na[N(SiMe(3))(2)] employed. Standard deviations in their diameter distributions are 5-15% of the mean diameters, consistent with near monodispersity. These Bi nanoparticles are shown to be the best currently available catalysts for the solution-liquid-solid (SLS) growth of high-quality CdSe quantum wires.
本文描述了一种从 BiCl(3) 和 Na[N(SiMe(3))(2)] 出发简便快捷地合成热稳定、近乎单分散的 Bi 纳米粒子的方法。通过改变 BiCl(3)和 Na[N(SiMe(3))(2)]的用量，可以将 Bi 纳米粒子的直径控制在 4-29nm 的范围内。其直径分布的标准偏差为平均直径的 5-15%，表明具有近单分散性。这些 Bi 纳米粒子是目前用于溶液-液-固（SLS）法生长高质量 CdSe 量子线的最佳催化剂。
