Analysis and characterization of coordination compounds by resonance Raman spectroscopy

Resonance Raman spectroscopy has become a powerful tool to study excited-state geometries, excited-state charge distributions and photoinduced reaction dynamics in coordination compounds. Due to their...

SQIF-based dc SQUID amplifier with intrinsic negative feedback

Optimization of a digital SQUID magnetometer in terms of noise and distortion

The digital SQUID magnetometer takes advantage of flux quantization in a superconducting loop in order to measure magnetic fields. Core element of the digital SQUID is a Josephson comparator with a superconducting...

MEMS: Fabrication of cryogenic bolometers

Cryogenic bolometers are among the most sensitive devices for the detection of electromagnetic radiation in the sub-millimeter range. Such radiation is of interest for astronomical observations as well...

Formaldehyde LIF detection with background subtraction around single igniting GTL diesel droplets

Formaldehyde is an important combustion intermediate, which is often used for the analysis of turbulent flames, internal combustion engines or droplet/spray ignition processes. Due to its high concentration...

Raman scattering and photoluminescence in silicon nanowire ensembles

Arrays of silicon (Si) nanowires with mean diameters of about 50–100 nm formed by wet-chemical etching of crystalline silicon wafers with low and high doping levels were investigated by means of photoluminescence...

Polymer-filled silica fibers as a step towards electro-optically tunable fiber devices

Microstructured fibers offer the possibility of being filled with unconventional materials in order to influence the propagation properties in an optical fiber waveguide. We have studied the filling of...

Nanofiber Fabry-Perot microresonator for nonlinear optics and cavity quantum electrodynamics

We experimentally realize a Fabry-Perot-type optical microresonator near the cesium D2 line wavelength based on a tapered optical fiber, equipped with two fiber Bragg gratings which enclose a sub-wavelength...

Light-Induced Dynamics in Conjugated Bis(terpyridine) Ligands – A Case Study Toward Photoactive Coordination Polymers

Terpyridine coordination compounds have recently revealed their potential toward optoelectronic applications, which are based on (i) their excellent charge-transfer properties or (ii) intriguing luminescence...
