An emission band in the infrared (IR) is shown to be associated with a transition within the negative nitrogen-vacancy centre in diamond. The band has a zero-phonon line at 1046 nm, and uniaxial stress and magnetic field measurements indicate that the emission is associated with a transition between 1E and 1A1 singlet levels. Inter-system crossing to these singlets causes the spin polarization that makes the NV- centre attractive for quantum information processing, and the IR emission band provides a new avenue for using the centre in such applications.

- Creation and nature of optical centres in diamond for single-photon emission—overview and critical remarks (2011, background): “The absence of luminescence centres in diamond emitting in the infrared at a wavelength longer than 1000 nm has been discussed in [85, 86].”
- Sensitivity optimization for NV-diamond magnetometry (2019, background): “First, the predominantly non-radiative decay of the 1A1 singlet greatly reduces the absorption cross section σ1042 of the 1E ↔1 A1 transition compared to a radiative-decay-only transition (Acosta et al., 2010b; Rogers et al., 2008).”
- Properties of nitrogen-vacancy centers in diamond: the group theoretic approach (2010, result): “This ordering has been discussed over the last few years [14, 16, 17], and our results agree with earlier [12] and recent ab initio calculations performed in bulk diamond [22].”
