Abstract

The recent surge in interest in the metal-enhanced fluorescence (MEF) phenomenon and its numerous applications in the biosciences has fueled research into identifying alternative metals to silver which have desirable properties, such as enhanced emission and fluorophore photostability. In this paper, we subsequently study and reveal that tin nanodeposits are a suitable metal for MEF with an electric field wavelength dependence somewhat different than silver. An enhanced fluorescence emission coupled with a reduced fluorophore lifetime suggests both an electric field and plasmon-coupling component are the underlying mechanisms for tin-based MEF. In addition, an enhanced fluorophore photostability is observed near-to tin nanodeposits.
