“…Photoluminescence has several origins in silicon particles, due to quantum size effects, excitonic radiation recombination pathways, surface traps, charge transfer from silicon to surface-bound ligands, and combinations of these effects. [1][2][3][4] Efforts to engineer both the silicon nanoparticle and the surface ligands have led to high quantum efficiencies, tunable emission colors, lifetimes and full width at half maximum band emissions. 5,6 Partially oxidized amorphous silicon nanostructures have been shown to display photoluminescence via radiative processes from surface or sub-surface defects.…”
