摘要：

We report a simple, two-step method for making magnetic, photoluminescent iron oxide ( magnetite) core/carbonaceous shell nanoparticles emitting blue light. The core-shell nanoparticles are created by an aqueous synthesis and functionalized in situ with three different organosilanes. Pyrolysis of the organosilane ligand shell at 200 degrees C yields water-dispersible core-shell particles visibly fluorescing under UV light.
