Nickel doped single crystal diamond layers were grown by nickel into the diamond layers was verified by secondary ion microwave-plasma enhanced chemical vapour deposition. mass spectrometry. Cathodoluminescence (CL) was applied to Optical emission spectroscopy (OES) utilised during growth reveal optically active defects related to nickel. The signature of proved that the organometallic compound nickelocene is an substitutionally incorporated nickel, namely the nickel related applicable nickel source. It was possible to produce stable and 1.4 eV centre, as well as the 2.369 and 1.563 eV centres were adjustable nickel OES signals during growth by altering the flux observed in CL. The latter is supposed to be a single-photon of the nickelocene carrier gas. The successful incorporation of emitter on the basis of a nickel-nitrogen defect centre.
