“…Two unidentified centers where only observed once: a color center emitting at 532 nm [87] and one at 734 nm [25] . Another type of unidentified single centers (named by the authors ST1) was reported in diamond nanowires structured into high-purity HPHT diamond using an inductively coupled plasma (ICP) dry etching process [88] .…”

“…Precisely such features are violated in a plethora of experimental findings ranging from electron/nuclear spins [16][17][18][19][20] or nitrogen-vacancy (NV) centers [21,22] to chromophoric molecules [23,24] which display a biexponential decay of the polarizations leading to two T 2 times, a short and a long one. This decay process was clearly associated to homogeneous non-Lorentzian susceptibility profiles in quantum dots (QDs) [25][26][27][28][29][30][31] and NV centers [32,33]. In addition, using materials doped with rare-earth ions, the decoherence can be slowed down by one order of magnitude for an initial Bloch vector being properly sized and oriented [34,35].…”

“…Notably, non-Lorentzian lineshapes were measured for nuclear spins [16], a wide range of QDs [25][26][27][28][29], NV centers [32,33] and for a quantum well [79]. Moreover, if one of the two contributions 6 The approximation ν = 0 at the numerator cannot be used to restore a combination of Lorentzian in case c ± and Λ± = 0 so that the profile is truly non-Lorentzian.…”

A quantum two-state system, weakly coupled to a heat bath, is traditionally studied in the Born-Markov regime under the secular approximation with completely positive linear master equations. Despite its success, this microscopic approach exclusively predicts exponential decays and Lorentzian susceptibility profiles, in disagreement with a number of experimental findings. To leave this limited paradigm, we use a phenomenological positive nonlinear master equation being both thermodynamically and statistically consistent. We find that, beyond a temperature-dependent threshold, a bifurcation in the decoherence time T 2 takes place; it gives rise to a biexponential decay and a susceptibility profile being neither Gaussian nor Lorentzian. This implies that, for suitable initial states, a major prolongation of the coherence can be obtained in agreement with recent experiments. Moreover, T 2 is no longer limited by the energy relaxation time T 1 offering novel perspectives to elaborate devices for quantum information processing.

“…In recent years, apart from the extensively studied optical center based on a substitutional nitrogen atom and a vacancy in the diamond matrix (NV center) [9], [10], several other complexes such as silicon vacancy (SiV) [11]- [14], previously unexplored single centers (Cr-related) [15], [16], a green emitter [17], H3 and H4 defects [18] and the TR12 center (interstitial carbon defect) [19] have been demonstrated to possess single-photon emission. In applications such as quantum information, metrology, nanoscopy, and biomarking, narrow-bandwidth spectral emissions, high brightness, and near-infrared emission are the properties underpinning ideal single-photon sources or more in general ideal fluorescent beads.…”

Fluorescent emitters in diamond are considered to be a valuable resource for fields such as quantum communication, quantum photonics, and biological imaging. In this paper, we report a wide range of narrow bandwidth (∼1.5 nm) spectral emission lines arising from different color centers at room temperature. The defects were created by chemical vapor deposition of thin diamond films grown on silica substrates seeded with nanoparticles of diamond and nickel. These fluorescent lines also possess single or few centers photon statistics. We correlate the zero-phonon lines, observed using confocal microscopy, with previously identified nickel-related centers which have been observed in high-pressure high-temperature diamond, with a Si/Ni complex and silicon vacancy defects. We compare our findings with recent results demonstrating single-photon emission in diamond associated with nickel-related centers to clarify and summarize previous studies concerning this specific dopant. The great variety of emission lines observed in the synthesized material, mainly associated with nickel-related centers, could be an important resource for applications relying on the presence of several emitters of single photons in the same sample. Moreover, the possibility of mass production of these centers in nanodiamonds in colloidal suspension may provide an important resource for biomarking and microscopy.Index Terms-Confocal microscopy, diamond defects, singlephoton emission.
