“…The HPHT annealing of such diamonds at T > 1900 K stimulates the migration of nitrogen atoms and their aggregations to form pairs (A centers) [31], and subsequently complexes containing up to four nitrogen atoms (B centers) [32]. Other NV complexes such as N 2 V (H3) [33] or N 3 V (N3) [34] may also be formed during annealing. Both impurities, nickel and nitrogen, can occur in different charge state: N can be 0 or (+1), while Ni can be from 0 to (+2) and varying charge states were shown in N-Ni complexes (NE1).…”

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.

“…The presence of H3 centers in unirradiated natural diamonds is quoted as evidence of plastic deformation. The H4 centers are formed from B defects via similar mechanism (Davies 1972), but they are not so abundant because the H4 centers dissociate to form more stable H3 centers at high temperatures (Collins et al 2005). The dominant role of H3 centers in PL spectra was noted even in diamonds with concentration of B defects being much higher than that of A centers (Collins et al 2005).…”

“…These centers are often observed in natural diamonds from different localities worldwide. In natural diamonds, the H3 center is known to be formed through trapping vacancies by two nitrogen atoms of A defects (Davies 1972). These vacancies can be generated by plastic deformation (Brookes et al 1993) and are associated with slip lines and dislocations (Hanley et al 1977).…”

“…N3 centers (415-nm peak) composed of three N atoms and a vacancy were detected in yellow diamonds, consistent with general findings for Cape yellow diamonds (Anderson, 1943). Additionally, the yellow Arg-16 diamond, which lacks deformation features, has an H3 center (503.2-nm peak), explained by Davies (1972) as two N atoms of A defects + vacancy. All the other yellow stones showing evidence of deformation have complicated PL spectra.…”

The Argyle lamproite mine is world famous for fancy colored diamonds, ranging from cognac and champagne shades of brown through Cape yellows to rare pink to intense red and even rarer blue stones. The majority of diamonds are type IaAB, displaying platelet degradation and having plastic and brittle deformation, mainly after diamond formation, indicative of high pressure/temperature conditions. The deformation produced optical defects, causing different Argyle diamond colors.White and brown Argyle diamonds belong to both eclogitic and peridotitic parageneses, but yellow-and pinkcolored ones studied here are eclogitic. Nitrogen contents, N aggregation states, and formation temperatures of yellow diamonds are correlated with their internal structure. The strongly deformed and internally brecciated yellow diamonds have low to moderate contents of highly aggregated N and high temperatures of formation. The undeformed yellow diamonds are richer in moderately aggregated N, and their formation temperatures are lower. The intensity of N3, H3, and H4 bands of the photoluminescence spectra of these diamonds is higher in the more deformed crystals.The pink eclogitic diamonds contain low to moderate N, are highly aggregated, and have high temperatures of formation, but differ from each other in the deformation level recorded by their internal structures. All identified photoluminescence peaks in these pink diamonds are higher in intensity in the strongly deformed crystals.Geothermometry, based on N contents, aggregation state, age, and temperature relationships of the diamonds, shows that most eclogitic diamonds resided at 1,250° to 1,300°C near the base of the lithospheric mantle, slightly deeper than the peridotitic diamonds. One eclogitic pink diamond contains a two-phase garnetomphacite inclusion reequilibrated from precursor majorite with composition indicative of formation pressure of 9.5 to 10 GPa, equivalent to ~300-km depth, the deepest identified for Argyle diamond formation to date. Internal structures of eclogitic diamonds reflect evidence of their formation under stress in a subduction zone setting.
