They serve as the electron donors to create the desired NV$^-$ center, provide charge stability against photo-ionisation, but also are the main source of decoherence. Therefore, precise and quick determination of N$_s^0$ concentration is a key advantage to a multitude of NV-related research in terms of material improvement as well as applications. Here we present a method to determine the N$_s^0$ concentration based on absorption spectroscopy in the UV-Visible range and fittin","authors_text":"F. A. Hahl, J. Jeske, J. Langer, L. Lindner, M.
