Silicon nanoparticles (Si NPs) have received great deal of attention due to their potential application as photodetectors, solar energy converters and chemical sensor devices. Si NPs show unique optoelectronic properties attributed to both quantum confinement and surface effects. The size of Si NPs can be controlled with the use of different surfactants. In addition, researchers are also interested in conjugating the Si inorganic core with an organic moiety which could change the electronic properties at the interface of these materials and benefit in solar energy conversion.       We will describe the synthesis and characterization of (2-10 nm) Si nanoparticles via reduction of the silicon salts. The effect of different organic surfactants, such as oleylamine and 1, 2- hexadecanediol and the effect of precursor concentrations on the size of the nanoparticles will be discussed. In addition, conjugation of the organic moieties such as phenyl groups to the Si NP surface to make hybrid inorganic/organic nanostructures will be presented.
