Large enhancement of single molecule fluorescence by coupling to hollow silver nanoshells.

ABSTRACT: We investigated the effect of plasmon-enhanced fluorescence using hollow silver nanoshells and observed enhancement of a single probe's fluorescence up to a factor of 3 orders of magnitude. The enhancement of the quantum efficiency is attributed to enhanced absorption and increased radiative decay rate.
