Profile 3. Sources on Frisian medieval history
Due to the fact that the Frisian lands lacked major political centers in the Middle Ages and also because most of its monasteries suffered complete destruction in the second half of the 16th century, relatively few written documents concerning medieval Frisian history have survived. To analyze them…

Plasmonic enhancement of single-molecule fluorescence under one- and two-photon excitation
This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…
