Abstract

Near-monodisperse Bi dots in the diameter range of 3- 115 nm are synthesized by a simple, solution-based one-step approach by varying the amounts of Bi[N(SiMe₃)₂]₃, Na[N(SiMe₃) ₂], and a polymer surfactant, poly(1-hexadecene)_0.67-co- (1-vinylpyrrolidinone)_0.33, employed. The reaction conditions are further modified to produce Bi nanorods and nanoplates. Alternatively, near-monodisperse Bi dots in the diameter range of 30-45 nm are synthesized by a secondary-addition technique. With a slight modification of this technique, nanoribbons are obtained. The roles of polymer and Na[N(SiMe₃) ₂] in the size and shape control of these Bi nanoparticles are discussed.
