Abstract
A process for converting bulk silicon into ultrasmall nanoparticles was described. Stimulated blue emission and second harmonic generation was exhibited from the films of ultrasmall silicon nanoparticles. A structural prototype for 29 silicon atoms was constructed giving a size, energy gap and an absorption spectrum using density functional and Monte carlo theory. It was found that atoms in these particles get subjected to unbalanced forces strong enough to reshape the molecular structure.
