Реферат: eng: The changes in the set and concentration of optically active defects in brown natural diamonds subjected to high pressure and high temperature annealing are studied. The darker brown color of the studied samples corresponds to stronger plastic deformation. The activation energy of the dissociation of the nitrogen pairs (defects A) decreases from 6.0 ± 0.4 eV in colorless samples with weak plastic deformation to 3.7 eV in dark brown samples with strong deformation. Possible defect transformation mechanisms are discussed. © Pleiades Publishing, Ltd., 2010.
