Fig. 6: An example of results for non-hybridization (Bright).
From: Simulating the dynamics of NV− formation in diamond in the presence of carbon self-interstitials

a An illustration of the absorption spectrum on all the non-hybridized situations. b A featured density of state (DOS) plot on the non-hybridized situation. c. A demonstration of transition on the electronic orbitals of the ground state (\(\bar{a}\)) to the excited states (\({\bar{e}}_{x}\) or \({\bar{e}}_{y}\)) of the NV centre at the wavelength of around 600 nm and a transition from the ground state (ex or ey) to the excited states (π) of interstitial carbon whose wavelength is around 1400 nm.
