An Easy Shortcut Synthesis of Size‐Controlled Bismuth Nanoparticles and Their Use in the SLS Growth of High‐Quality Colloidal Cadmium Selenide Quantum Wires

Abstract 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.
