The unique properties of nitrogen-vacancy (NV) centers in diamond allow to use them as efficient quantum sensors even at room temperature. An example application is NMR spectroscopy on nuclear spin ensembles transferred on the diamond surface using single NV centers few nanometers below the surface. The measurement sensitivity is fundamentally dependent on the spin's lifetime, which is mainly limited by NV centers' environment. In addition, diamond surface properties influence stability of shallow NV centers. We investigate few layered phosphorene flakes deposited on diamond for their possible application as a quantum simulator, but this material degrades under ambient conditions. We present a confocal microscope with a glovebox enclosure for performing NV-based NMR spectroscopy on multi-layered phosphorene.
