Abstract

The radiative decay rates of perylene dye molecules, attached to silicon nano-rods are investigated by means of time-resolved fluorescence experiments. The decay rates of dye molecules in the vicinity of silicon nano-rods are inhibited due to their various diameters and therefore the modification of the surrounding environment. Inhibition is caused by an increased nonradiative rate due to resonant energy transfer described by the Gersten-Nitzan model.
