Abstract
The invention concerns elemental silicon emission devices. Devices according to the invention use elemental silicon nanoparticles as a material from which stimulated emissions are produced. Silicon nanoparticles efficiently produce emissions and act as a gain medium in response to excitation. The silicon nanoparticles of the invention, being dimensioned on an order of magnitude of one nanometer and having about 1 part per thousand or less larger than 1 nm, are an efficient emission source and forms the basis for many useful devices.
