Using shallow implantation of ions and molecules with masses centred at 27 atomic mass units(amu)
in diamond, a new artificial optical centre with unique properties has been created. The centre shows a
linearly polarised fluorescence with a main narrow emission line mostly found at 582 nm, together
with a weak vibronic sideband at room temperature. The fluorescence lifetime is∼2 ns and the
brightest centres are more than three times brighter than the nitrogen-vacancy centres. A majority of
the centres shows stable fluorescence whereas some others present a blinking behaviour, at faster or
slower rates. Furthermore, a second kind of optical centre has been simultaneously created in the same
diamond sample, within the same ion implantation run. This centre has a narrow zero-phonon line
(ZPL) at∼546 nm and a broad phonon sideband at room temperature. Interestingly, optically
detected magnetic resonance (ODMR) has been measured on several single 546 nm centres and two
resonance peaks are found at 0.99 and 1.27 GHz. In view of their very similar ODMR and optical
spectra, the 546 nm centre is likely to coincide with the ST1 centre, reported once (with a ZPL at
550 nm), but of still unknown nature. These new kinds of centres are promising for quantum
information processing, sub-diffraction optical imaging or use as single-photon sources.
