A new approach for the chemical synthesis of colloidal indium antimonide (InSb) nanocrystals is reported. It relies on the in situ generation of stibine gas (SbH3) as the antimony precursor and yields highly crystalline particles with a mean diameter of 8.8 nm and low size dispersion (13%). A synthetic pathway for the preparation of larger particles (≈100 nm) is also presented.
