The recombination of oxygen atoms on the Zn2SiO4-Mn surface was studied by nonstationary methods based on the use of an atomic attenuator. The recombination of oxygen atoms was shown to occur on the surface predominantly via the Rideal-Eley mechanism, although there was a certain contribution of the diffusion Langmuir-Hinshelwood mechanism. The identification of the mechanisms was based on the detection of changes in the intensities of luminescence caused by excited oxygen atoms, which recombinate on the willemite surface, under various conditions of excitation: the density of the flow of oxygen atoms and temperature of the sample. The kinetic mechanism of recombination of oxygen atoms and excitation of luminescence on the Zn2SiO4-Mn surface was modelled.
