EPR studies of a nickel-boron centre in synthetic diamond
Possible models are discussed for a new EPR centre (NOL1) observed in a diamond grown from a nickel-containing solvent catalyst with a titanium nitrogen getter. Nickel and boron are the most prevalent impurities in the diamond. The centre has trigonal (C-3v) symmetry about <111>, S = 1...

| description | Possible models are discussed for a new EPR centre (NOL1) observed in a diamond grown from a nickel-containing solvent catalyst with a titanium nitrogen getter. Nickel and boron are the most prevalent impurities in the diamond. The centre has trigonal (C-3v) symmetry about <111>, S = 1, g(11) = 2.0235 (5), g(perpendicular to) = 2.0020(10) and D = - 171(1) GHz. The EPR lineshape is unusual and we tentatively attribute this to partially resolved B-11 hyperfine structure. This centre may be the same as NIRIM-5, observed in boron doped synthetic diamond. The most likely structure for this centre is an interstitial Ni2+ with a substitutional B- ion at the nearest neighbour site along <111>. (C) 2002 Elsevier Science B.V. All rights reserved. |
