Trapped in Imidazole – How to Accumulate Multiple Photoelectrons on a Black Absorbing Ruthenium Complex
The design of light-driven multi-electron photocatalysts, e.g., for hydrogen generation requires (i) the development of efficient two electron redox pathways, which meet the energetic and kinetic requirements...
PublikationenResonance-Raman spectro-electrochemistry of intermediates in molecular artificial photosynthesis of bimetallic complexes
The sequential order of photoinduced charge transfer processes and accompanying structure changes were analyzed by UV-vis and resonance-Raman spectroscopy of intermediates of a Ru(II) based photocatalytic...
PublikationenOptical Sapphire Fiber Bragg Gratings as High Temperature Sensors
Fiber Bragg gratings (FBG) were inscribed in single crystalline sapphire fibers by fs-laser irradiation. Due to the used multi-mode air clad fiber a sapphire-FBG spectra showa a wide asymmetric peak with...
PublikationenDiffusion in binary TiO2- SiO2 glasss
The diffusion of titanium in TiO2-SiO2 glasses with up to 7 mol% TiO2 was investigated by annealing doped layers on the inner surface of quartz glass tubes between 1700 and 2000°C and measuring radial...
PublikationenA highly efficient Yb-doped silica laser fiber prepared by gas phase doping technology
In this paper we report on an alternative technique for the preparation of ytterbium (Yb)doped silica fibers and their characteristics compared to the conventional modified chemical vapor deposition (MCVD)...
PublikationenLight-triggered CO release from nanoporous non-wovens
The water insoluble and photoactive CO releasing molecule dimanganese decacarbonyl (CORM-1) has been non-covalently embedded into poly(L-lactide-co-D/L-lactide) nanofibers via electrospinning to enable...
PublikationenFormation of self-trapping waveguides in bulk PMMA media doped with Phenanthrenequinone
Experimental and theoretical investigations of light self-trapping waveguides in a bulk polymeric medium based on polymethylmethacrylate (PMMA) with photosensitive phenanthrenequinone (PQ)-molecules are...
PublikationenRaman fiber probes – Current development and future trends
Raman spectroscopy has been proven to be a powerful bio-diagnostically tool. With this technique several biomedical questions were addressed, e.g. tumor detection, cell differentiation, the in-vivo arteriosclerotic...
PublikationenAccumulating advantages, reducing limitations: Multimodal nonlinear imaging in biomedical sciences – the synergy of multiple contrast mechanisms
Multimodal nonlinear microscopy has matured during the past decades to one of the key imaging modalities in life science and biomedicine due to its unique capabilities of label-free visualization of tissue...
PublikationenTuning of Spectral and Angular Distribution of Scattering from Single Gold Nanoparticles by Subwavelength Interference Layers
Localized surface plasmon resonance (LSPR) as the resonant oscillation of conduction electrons in metal nanostructures upon light irradiation is widely used for sensing as well as nanoscale manipulation....
