Abstract

Bismuth nanoparticles have been produced by the oxidation of the Zintl polyanion Bi 4 2− in ethylenediamine solutions. TEM images indicate that the crystalline nanoparticles produced in the presence of polyethylene glycol are in the size range of ∼20 nm. The oxidation of the polyanion by 2‐octanol produce larger nanoparticles of bismuth (∼50 nm).
