Abstract
Section titled āAbstractāDiamond based nitrogen-vacancy (NV) centers are promising solid state defects for applications in quantum information technologies. On the one hand, there is a growing interest in enhancing their single-photon emission by coupling them to plasmonic structures. On the other hand, the dependence of emission intensity on the electron spin state enables room temperature quantum information readout. We study the fluorescence contrast resulting from the spin resonance in the conditions of an increased photonic density of states. Fluorescence observations from NV center ensembles in diamond nanocrystals coupled to structures supporting plasmonic modes experimentally confirm the analytical results.
