Electron paramagnetic resonance of Cu 2+(d 9) has been detected optically in the visible and near-infrared luminescence of wurtzite GaN. Its effective S= 1/2 spin Hamiltonian parameters are g‖=±0.20 (5), g⊥=+ 1.549 (1), and| 63 A‖|= 550 (50) MHz, and| 63 A⊥|= 570 (5) MHz. A crystal field theory of the g values is presented, which identifies the ion as substitutional on the Ga sublattice. Possible mechanisms for its presence in the luminescence are discussed.
