Abstract

The present invention provides a method for preparing nanoparticles of group IV elements, particularly nanoparticles of Si, Ge and Sn, and binary and ternary alloys of these elements. The method comprises the solution-phase decomposition of one or more group IV metal precursors at elevated temperature and under an inert atmosphere at atmospheric pressure, using a decomposition-promoting reagent. A surface-bonding agent is added to the reaction mixture to form an organic layer surrounding the nanoparticles and prevent aggregation.
