Metal-Enhanced Fluorescence and FRET in Multilayer Core-Shell Nanoparticles

Figure 6

Extinction spectra of Ag@SiO2@SiO2 + EiTC NPs (upper curve) and corresponding hollow silica nanoshells (lower curves). Silica spacer shell thickness was 7 ± 2 nm, concentration of EiTC was 4 mM in the core-shell nanoparticles (upper curve) and from 0 to 87 mM in hollow silica shells (lower curves).
