1. A light emitting device, comprising:

  • a plurality of nanoparticles, the nanoparticles comprising a Group IV metal selected from the group consisting of silicon, germanium and tin and a capping agent coupled to the Group IV metal which inhibits oxidation of the nanoparticles, wherein the nanoparticles have an average particle diameter of between about 1 to about 100 angstroms; and

    an anode electrically coupled to the plurality of nanoparticles; and

    a cathode electrically coupled to the plurality of nanoparticles;

    wherein the anode and cathode together are configured to conduct an applied current to the nanoparticles, wherein the nanoparticles produce light in response to the applied current.
