Abstract

IPCicon nanoparticles and metal-centered silicon nanoparticles and solution phase methods of synthesis using commonly available reagents and ordinary conditions. Solvent may be diglyme, triglyme, tetraglyme, even in mixture with nonpolar solvent. A halosilane is reduced with metal, for example, at reflux conditions. Reaction product is hydrolyzed or passivated to produce stable subunit that can agglomerate or polymerize into larger structures. Particle size synthesized can be controlled. These particles and structures are photoluminescent and suitable for various applications, including light emitting devices.
