ABSTRACT:
Highly uniform 1 nm silicon nanoparticles are provided by the invention. The nanoparticles exhibit beneficial properties. They are a source of stimulated emissions. They may be suspended in liquids, and solids. They can be formed into crystals, colloids and films. The nanoparticles of the invention are about 1 nm having about only one part in one thousand greater than 1 nm. A method for producing the silicon nanoparticle of the invention is a gradual advancing electrochemical etch of bulk silicon. Separation of nanoparticles from the surface of the silicon may also be conducted. Once separated, various methods may be employed to form plural nanoparticles into colloids, crystals, films and other desirable forms. The particles may also be coated or doped.
