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…
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…
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…
