An approach has been made for the synthesis of silicon nanoparticles by an improvement in the solution reduction method. In particular, the use of metal naphthalenides has been reported as precursors to silicon nanoparticles with subsequent surface derivatization with organic ligands. We describe the synthesis and characterization of Si nanoparticles prepared by the soluton reduction of SiCl4 by lithium naphthalenide and subsequently with n-BuLi at room temperature. These reactions produce Si nanoparticles with surfaces that are covalently terminated with C4H9-group. The resultant nanoparticles can be suspended in hexane and water and characterized by photoluminescence(PL) spectroscopy and X-ray diffraction pattern(XRD). This work focuses originally on the organic- and water-soluble silicon nanoparticles in terms of the photoluminescence.
