Nanoparticles with grafted organic molecules
First Claim
1. A method of producing substantially non-agglomerated, grafted Group IV nanoparticles, comprising:
- synthesizing substantially nonagglomerated Group IV nanoparticles;
receiving the substantially nonagglomerated Group IV nanoparticles in a gas phase wherein the nanoparticles are suspended in the gas phase;
creating a plasma or an afterglow of a plasma to immerse the nonagglomerated nanoparticles and thereby causing the nonagglomerated nanoparticles to become negatively charged;
providing organic molecules to the nanoparticles; and
allowing the organic molecules to break down and/or become activated in the plasma or in the afterglow of the plasma and bond with the nanoparticles thereby forming organic passivation layers comprising carbon hydrogen bonds on the nanoparticles, wherein the passivation layers are bonded to the nanoparticles while in the plasma or in the afterglow of the plasma.

Abstract
An apparatus for producing grafted Group IV nanoparticles is provided and includes a source of Group IV nanoparticles. A chamber is configured to carry the nanoparticles in a gas phase and has an inlet and an exit. The inlet configured to couple to an organic molecule source which is configured to provide organic molecules to the chamber. A plasma source is arranged to generate a plasma. The plasma causes the organic molecules to break down and/or activate in the chamber and bond to the nanoparticles. A method of producing grafted Group IV nanoparticles is also provided and includes receiving Group IV nanoparticles in a gas phase, creating a plasma with the nanoparticles, and allowing the organic molecules to break down and/or become activated in the plasma and bond with the nanoparticles.
