Blue-Emitting Polymers Based on 4-Hydroxythiazoles Incorporated in a Methacrylate Backbone
The synthesis of two new monomers based on 4-hydroxythiazoles, with a non-classical chromophore structure similar to the luciferin dye of glowworms, is presented. These dyes are functionalized with methacrylates...
PublikationenA Heteroleptic Bis(tridentate) Ruthenium(II) Complex of a Click-Derived Abnormal Carbene Pincer Ligand with Potential for Photosensitzer Application
Long live the complex! A heteroleptic ruthenium(II) complex of a click-derived tridentate triazolylidene ligand (see graphic) and the parent terpyridine were prepared and investigated by experimental and...
PublikationenClassification of novel thiazole compounds for sensitizing Ru–polypyridine complexes for artificial light harvesting
A systematical study of the Förster resonance energy transfer (FRET) efficiency between thiazole dyes and a Ruthenium polypyridine complex is presented. While Ruthenium polypyridines are conventionally...
PublikationenMicrofabricated atomic vapor cell arrays for magnetic field measurements
We describe a method for charging atomic vapor cells with cesium and buffer gas. By this, it is possible to adjust the buffer gas pressure in the cells with good accuracy. Furthermore, we present a new...
PublikationenOperation and Accuracy of an Automated Cryocooler-based 10 Volt Josephson Voltage Standard System
A commercially available complete microprocessor controlled, fully automated 10 Volt Josephson voltage standard system operated with a cryocooler was developed in cooperation between IPHT and Supracon....
PublikationenMicrowave properties of microstrip line circuits used for Josephson voltage standard arrays at 70 GHz
The microwave properties of microstrip lines used for Josephson voltage standard circuits at frequencies from 70 GHz to 75 GHz were investigated for temperatures of 4.2 K. The work focuses on the microwave...
PublikationenDisorder control of Tc in thin film molybdenum
We have looked at the dependence of the superconducting transition temperature on the deposition parameters of magnetron sputtered Mo on Si3N4 coated Si substrates. From the measurements we can conclude...
PublikationenFemtosecond relaxation kinetics of highly excited MNa** states in CaF2 at 3.2 eV and 4.7 eV
Femtosecond (fs) laser pulses at variable delay times allowed to track the fast non-radiative transitions between the manifold of highly excited MNa** states to the lower lying fluorescent MNa* state in...
PublikationenDetermination of the photoluminescence quantum efficiency of silicon nanocrystals by laser-induced deflection
The oxidation and passivation of freshly prepared silicon nanocrystals Si NCs have been studied by exciting them with a low-fluence violet laser at 406 nm and measuring both the heat generated by nonradiative...
PublikationenLaser induced deflection technique for absolute thin film absorption measurement: optimized concepts and experimental results
Using experimental results and numerical simulations, two measuring concepts of the laser induced deflection (LID) technique are introduced and optimized for absolute thin film absorption measurements...
