Paper Abstract

Luminescent emission from lanthanide complexes on silver island films has been studied. Silver films with and without silica spacer layers have been prepared chemically and by thermal vacuum deposition. Enhancement of emission from lanthanide complexes on silver compared to that on bare glass depends on the optical density of the silver films (silver coverage) and sample coverage. A silica spacer layer reduces the number of molecules in quenching regions of the film and leads to better enhancement. Lanthanides with lower quantum efficiencies are expected to exhibit greater enhancement factors and our preliminary results are consistent with that prediction.
