Low-field optically detected magnetic resonance of a coupled triplet-doublet defect pair in diamond

Low-field optically detected magnetic resonance of a coupled triplet-doublet defect pair in diamond.

Microwave-induced changes in the optical emission of the NV center in diamond have previously been attributed to magnetic resonance of the defect in its A ground state [E. van Oort et al. , J. Phys. C 21, 4385 (1988)]. In this paper, the focus is on the origin of the hyperfine splittings that are observed in the optically detected magnetic-resonance (ODMR) spectra at zero and low magnetic field...

Excited-state spectroscopy of single NV defect in diamond using optically detected magnetic resonance

Using pulsed optically detected magnetic resonance techniques, we directly probe electron-spin resonance transitions in the excited-state of single Nitrogen-Vacancy color centers in diamond. Unambiguous assignment of excited state fine structure is made, based on changes of NV defect photoluminescence lifetime. This study provides significant insight into the structure of the emitting E excited...
