Figure 1

(a) Photoluminescence spectra of allylbenzyl-capped silicon nanoparticle (ncSi:AB) fractions show a blue shift in the photoluminescence maxima with increasing fraction number (and overall decreasing size); inset: photo of ncSi:AB fractions under UV illumination. (b) Plot shows size distribution of selected ncSi:AB fractions. (c) High-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) image of fraction 4. (d) HAADF-STEM image of fraction 10. Scale bars = 20 nm.
