Аннотация: Synthetic diamonds grown at high pressure and high temperature by spontaneous crystallization using a nickel catalyst and europium oxide additive exhibit emission spectra caused by a large morphological diversity of luminescence centers. It was found that most emission lines are associated with complex impurity centers of the NiN_x composition (consisting of several nickel and nitrogen atoms) in a covalent diamond lattice. It was shown that the addition of europium oxide promotes an increase in the concentration of nickel Ni_s⁻ centers in the crystals.

Ключевые слова: synthetic diamond, high pressure and high temperature, nickel–nitrogen complexes, luminescence, electron spin resonance, solid state chemistry.
