High temperature sensing with fiber Bragg gratings in sapphire-derived all-glass optical fibers
A structured sapphire-derived all-glass optical fiber with an aluminum content in the core of up to 50 mol% was used for fiber Bragg grating inscription. The fiber provided a parabolic refractive index...
PublikationenFiber-based optical parametric oscillator for high resolution coherent anti-Stokes Raman scattering (CARS) microscopy
Imaging based on coherent anti-Stokes Raman scattering (CARS) relies on the interaction of high peak-power, synchronized picosecond pulses with narrow bandwidths and a well-defined frequency difference....
PublikationenAmnesic shellfish poisoning biotoxin detection in seawater using pure or amino-functionalized Ag nanoparticles and SERS
Domoic acid (DA) biotoxin responsible for the amnesic shellfish poisoning (ASP) has been unambiguously detected in seawater in a broad range of concentration, with both pure and amino-functionalized Ag...
PublikationenIsolation and identification of bacteria by means of Raman spectroscopy
Bacterial detection is a highly topical research area, because various fields of application will benefit from the progress being made. Consequently, new and innovative strategies which enable the investigation...
PublikationenShedding light on host niches: label-free in situ detection of Mycobacterium gordonae via carotenoids in macrophages by Raman microspectroscopy
Macrophages are the primary habitat of pathogenic mycobacteria during infections. The current research about the host pathogen interaction on the cellular level is still going on. The present study proves...
PublikationenResonance at the Rabi Frequency in a Superconducting Flux Qubit
We analyze a system composed of a superconducting flux qubit coupled to a transmission-line resonator driven by two signals with frequencies close to the resonator’s harmonics. The first strong signal...
PublikationenPowder-sintering Technique for High-power Fiber Lasers
A new approach for silica laser materials is presented. The technology is based on reactive powder doping, sintering and vitrification and yields in homogeneous active doped bulk material with an excellent...
Publikationena-Si:H/c-Si Heterojunction solar cell based on top-down silicon nanostructures
The properties of (n)a-Si:H/(p)c-Si heterojunction solar cells based on wet chemically etched silicon nanowires with different architectures are explored. Heterojunction solar cell based on silicon nanostructures...
PublikationenNew Ruthenium Bis(terpyridine) Methanofullerene and Pyrrolidinofullerene Complexes: Synthesis and Electrochemical and Photophysical Properties
A series of terpyridine (tpy) methanofullerene and pyrrolidinofullerene dyads linked via p-phenylene or p-phenyleneethynylenephenylene (PEP) units is presented. The coordination to ruthenium(II) yields...
PublikationenStructure-Property Relationships in an Iridium(111) Bis(Terpyridine) Complex with Extended Conjugated Side chains
Iridium(III)-bis-terpyridine complexes are known as excellent triplet emitters with emission lifetimes in the order of microseconds. We report the homoleptic complex [IrL2]3+ (L = 4’-(4-2,5-bis(octyloxy)-4-styrylphenyl)ethinyl)phenyl)-2,2’:6’,2’’-terpyridine)...
