Large enhancement of fluorescence from CdSe/ZnS quantum dots induced by resonant coupling to spatially controlled surface plasmons

Nanoengineered fluorescent response is reported in semiconductor core-shell (CdSe/ZnS) quantum dots in proximity to the surface plasmon field of periodic silver nanoparticle arrays. Tuning the surface plasmon resonance to the quantum dot exciton emission band results in an /spl sim/50-fold enhanceme...

Description
Summary:Nanoengineered fluorescent response is reported in semiconductor core-shell (CdSe/ZnS) quantum dots in proximity to the surface plasmon field of periodic silver nanoparticle arrays. Tuning the surface plasmon resonance to the quantum dot exciton emission band results in an /spl sim/50-fold enhancement of the fluorescence.
