Towards Application of Nanodiamonds for in-situ Monitoring of Radicals in Liquid Phase Chemical Reactions
Emma Herbst, Sebastian Westrich, Alena Erlenbach +3
In many chemical reactions, short-lived radical intermediates play a crucial role, while detecting such short-lived species in-situ remains challenging. The optically readable elec…
Characterization of Autofluorescence in Optical Fibers for NV-based Sensing Applications
Stefan Johansson, Alexander Bukschat, Dennis Lönard +3
Optical fibers are crucial for guiding light in various sensing applications. Especially for quantum sensors such as the nitrogen-vacancy (NV) center in diamond, they enable light…
Limits of absolute vector magnetometry with NV centers in diamond
Dennis Lönard, Isabel Cardoso Barbosa, Stefan Johansson +2
The nitrogen-vacancy (NV) center in diamond has become a widely used platform for quantum sensing. The four NV axes in mono-crystalline diamond specifically allow for vector magnet…
Probing the fluctuating magnetic field of Fe-triazole spin-crossover thin-layers with nitrogen-vacancy centers in diamond
Isabel Cardoso Barbosa, Tim Hochdörffer, Juliusz A. Wolny +5
Fe spin-crossover (SCO) complexes are materials that change their magnetic properties upon temperature variation, exhibiting a thermal hysteresis. Particularly inte…
Miniaturized magnetic-field sensor based on nitrogen-vacancy centers
Stefan Johansson, Dennis Lönard, Isabel Cardoso Barbosa +3
The nitrogen-vacancy (NV) center in diamond is a prime candidate for quantum sensing technologies. Here, we present a fully integrated and mechanically robust fiber-based endoscopi…
Temperature dependence of charge conversion during NV-center relaxometry
Isabel Cardoso Barbosa, Jonas Gutsche, Dennis Lönard +2
Temperature-dependent nitrogen-vacancy (NV)-center relaxometry is an established tool to characterize paramagnetic molecules near to a sensing diamond, gaining momentum in differen…
Impact of Charge Conversion on NV-Center Relaxometry
Isabel Cardoso Barbosa, Jonas Gutsche, Artur Widera
Relaxometry schemes employing nitrogen-vacancy (NV) centers in diamonds are essential in biology and physics to detect a reduction of the color centers' characteristic spin relaxat…
Fiber-tip endoscope for optical and microwave control
Stefan Dix, Jonas Gutsche, Erik Waller +2
We present a robust, fiber based endoscope with a silver direct-laser-written (DLW) structure for radio frequency (RF) emission next to the optical fiber facet. Thereby, we are abl…
Revealing Collective Emission in the Single-to-Bulk Transition of Quantum Emitters in Nanodiamond Agglomerates
Jonas Gutsche, Ashkan Zand, Marek Bültel +1
Individual quantum emitters form a fundamental building block for emerging quantum technologies. Collective effects of such emitters might improve the performance of applications e…
Coherent Remote Control of Quantum Emitters Embedded in Polymer Waveguides
Alexander Landowski, Jonas Gutsche, Stefan Guckenbiehl +3
We report on the coherent internal-state control of single crystalline nanodiamonds, containing on average 1200 nitrogen-vacancy (NV) centers, embedded in three-dimensional direct-…
