Abstract: | Nanometer
sized silicon particles were prepared by laser vaporization of a silicon target in pure argon
ambient at a reduced pressure. The shape and size of the nanoparticles were characterized by
transmission electron microscopy. The as prepared nanometer silicon particles exhibit visible
luminescence under light excitation and the activated light emissions are found to show a
strong dependence on temperature. |
