Charge-Selective Raman Scattering and Fluorescence Quenching by “Nanometal On Semiconductor” Substrates

Ag nanoparticles synthesized on n and p-type Si were shown to exhibit charge-selective surface-enhanced Raman scattering and fluorescence quenching. As revealed by electric force microscopy, the polarity and magnitude of the nanoparticle charge is controllable with the metal-semiconductor Fermi leve...
