Paper Abstract

We report our experimental observations of variation in on-off statistics and fluorescence intensity of single Rhodamine6G molecules in presence of resonantly driven surface plasmon of silver nanoparticle. Derived lifetimes from on-off statistics of fluorophore show that interaction between the fluorophore and the subwavelength metal nanoparticle improves photostability and enhances fluorescence intensity. This enhancement follows the trend predicted by the dipole-dipole interaction model.
