Abstract
The polarization of luminescence of the 2.989 eV (4150 Å) and 2.464 eV (5032 Å) centres in diamond as a function of the energy of excitation is compared with the excitation spectra of these centres. The results are interpreted in terms of two electric dipole transitions in both types of centre. The 2.989 eV and 3.602 eV absorption lines are shown to be associated with a defect of trigonal symmetry, while the 2.464 eV and 3.368 eV absorption lines are associated with a defect of monoclinic I symmetry.Keywords
