| Surface plasmon resonance of metallic nanoparticles has attracted much attention in the past few decades due to its tremendous impact on many photo-chemical and photo-physical processes of molecules. Many important applications including molecular sensing, catalysis, nanolithography and near field optical microscopy utilize the phenomenon. We investigated the influence of surface plasmon resonance of nanotextured silver film on the radiative decay processes of molecular systems. The photoluminescence intensity of dye molecules was enhanced up to tens of times for certain circumstances and we used a photophysical model to interpret the enhancement in terms of absorption enhancement and increased radiative decay rate caused by molecule-plasmon interactions. Possible applications in organic electronics and preliminary results will be discussed. |
