Paper Abstract

We propose a Fluorescent Scanning Near-Field Optical Microscope (FSNOM) based upon the measurement of the decay time of a fluorescent particle adsorbed on a SNOM tip. The purpose of the experiment is to measure the decay time variations of the fluorescent particle when the tip is scanned at a few nanometers from the surface of a sample. We describe the experimental set-up and present a theoretical model: it calculates, by a perturbation method, the variations of the life-time on a rough surface. The formalism is rapidly described and first theoretical life- time signals are presented.
