Seeing the Unseen -- Boosted Absorption Imaging and Spectroscopy Using a Scanning Microresonator
Jonathan Noé, Michael Förg, Manuel Nutz +5
Optical detection of nanoscale objects without relying on fluorescence is a current challenge due to their extremely weak interaction with light. Resonator-enhanced absorption micr…
Picosecond time-resolved antibunching measures nanoscale exciton motion, annihilation, and true number of chromophores
Gordon J. Hedley, Tim Schröder, Florian Steiner +8
The particle-like nature of light becomes evident in the photon statistics of fluorescence of single quantum systems as photon antibunching. In multichromophoric systems, exciton d…
Interchromophoric Interactions Determine the Maximum Brightness Density in DNA Origami Structures
Tim Schröder, Max B. Scheible, Florian Steiner +2
An ideal point light source is as small and as bright as possible. For fluorescent point light sources, homogeneity of the light sources is important as well as that the fluorescen…
Determining the True Optical Gap in a High-Performance Organic Photovoltaic Polymer Using Single-Molecule Spectroscopy
Gordon J. Hedley, Florian Steiner, Jan Vogelsang +1
Low-gap conjugated polymers have enabled an impressive increase in the efficiencies of organic solar cells, primarily due to their red absorption which allows harvesting of that pa…
Role of Triplet-State Shelving in Organic Photovoltaics: Single-Chain Aggregates of Poly(3-hexylthiophene) versus Mesoscopic Multichain Aggregates
Florian Steiner, John M. Lupton, Jan Vogelsang
Triplet excitons have been the focus of considerable attention with regards to the functioning of polymer solar cells, because these species are long-lived and quench subsequently…
Spectral focusing of broadband silver electroluminescence in nanoscopic FRET-LEDs
Robin P. Puchert, Florian Steiner, Gerd Plechinger +10
Few inventions have shaped the world like the incandescent bulb. While Edison used thermal radiation from ohmically heated conductors, some noble metals exhibit "cold" electrolumin…
Differentiation between shallow and deep charge trap states on single poly(3-hexylthiophene) chains through fluorescence photon statistics
Kristin S. Grussmayer, Florian Steiner, John M. Lupton +2
Blinking of the photoluminescence (PL) emitted from individual conjugated polymer chains is one of the central observations made by single-molecule spectroscopy (SMS). Important in…
Fluctuating exciton localisation in giant pi-conjugated spoked-wheel macrocycles
Vikas Aggarwal, Alexander Thiessen, Alissa Idelson +8
Conjugated polymers offer potential for many diverse applications but we still lack a fundamental microscopic understanding of their electronic structure. Elementary photoexcitatio…
Unraveling the chromophoric disorder of poly(3-hexylthiophene)
Alexander Thiessen, Jan Vogelsang, Takuji Adachi +3
The spectral breadth of conjugated polymers gives these materials a clear advantage over other molecular compounds for organic photovoltaic applications and is a key factor in rece…
Spontaneous fluctuations of transition dipole moment orientation in OLED triplet emitters
Florian Steiner, Sebastian Bange, Jan Vogelsang +1
The efficiency of an organic light-emitting diode (OLED) depends on the microscopic orientation of transition dipole moments of the molecular emitters. The most effective materials…
Singlet-triplet annihilation limits exciton yield in poly(3-hexylthiophene)
Florian Steiner, Jan Vogelsang, John M. Lupton
Control of chain length and morphology in combination with single-molecule spectroscopy techniques provide a comprehensive photophysical picture of excited-state losses in the prot…
