dc.description.abstractengIn this work, we show how a profound theoretical understanding of a seemingly exotic phenomenon, namely the influence of metal structures on fluorescence lifetimes, has lead to the development of a microscopy technique with outstanding z-resolution that is based on a completely different physical concept than other optical super-resolution methods. The first part of this work is dedicated to classical electrodynamics. In particular, the radiation properties of oscillating electric dipoles are derived in both planar and spherical geometries. An interpretation of these results in quantum-mechanical terms is then used to quantitatively describe the change of fluorescence lifetimes in the vicinity of metal nanostructures. The power of this semi-classical approach is demonstrated in the second part of this work, where metal-induced energy transfer (MIET) microscopy is employed to study several biological systems, and the fluorescence quantum yield of dyes in different environments is determined via lifetime measurements in a
