FIG. 2.

(a)-(c) SEM cross-sectional images of Si nanorods’ structure at different magnifications after functionalization and attachment at high concentration of NQDs. Well resolved individual NQDs are seen on panel (c)

Image of FIG. 3.
FIG. 3.

(Color online) (a) PL spectra of NQDs grafted on glass, planar Si and Si-nanopillars for similar starting NQD concentrations. Inset: Schematics of nanopillar structure (b) PL decays for the same set of samples. Dashed lines are fits to monoexponential decays (top and middle curves) and to biexponential decay (bottom curve).
