Fluorescence Enhancement and Quenching in Tip-Enhanced Fluorescence Spectroscopy

Frontiers in Optics / Laser Science, 2018
We study fluorescence enhancement for a dipole emitter placed between a tip and different dielectric substrates. Resonant behavior is observed as a function of tip-substrate distance for a silver tip placed above a glass substrate and displays a strong dependence on the radius of the curvature of the tip.
