Bismuth nanoparticles specifically have become interesting for their electric properties and use for thin films. Bulk bismuth has very unique electrical properties. For instance it has a very low carrier density and is a highly anisotropic Fermi surface. In addition, bismuth nanoparticles have shown potential for having even larger thermoelectric effects than bulk bismuth. This study focuses on the synthesis, characterization and stabilization of bismuth nanoparticles made from Bi(N(SiMe3)2)3. The reproducible synthesis makes nanoparticles ranging from 1-4 nm where most of the stabilization is done by Li or Na -HMDS, along with a byproduct of the reaction. We note the strength of the diamagnetism of bismuth by observing a shift of ligands present in the nanoparticles solution. Any additional shift is due to a particular ligand helping stabilize the nanoparticles. By this method we can tell which ligand stabilizes the bismuth nanoparticles.
