From: Octahedral faceted Si nanoparticles as optical traps with enormous yield amplification
Raman yield (a) and amplification (b) calculated according to eq. (3) in several samples, each covered by Si-NPs with an increasing amount of nanoparticles.
The amplification G systematically decreases with increasing Si-NP density for any fixed nanoparticle volume. The solid line in (b) is a linear fit to G as calculated by eq. (3).
