Abstracts

EN

Absorption and reflectivity measurements were carried out on Zn_{1-x}Mn_{x}Se:Ni solid solutions. The spectra demonstrate the radical change of the structure of internal Ni^{2+}(3d^{8}) transitions at the presence of the Mn ions and strong dependence on Mn concentration. The threshold energy ħω_{th} for the process of Ni photoionization to the valence band Ni^{2+}(3d^{8}) + ħω_{th} → Ni^{1+}(3d^{9}) + h is shifted to the lower energy by 30 meV, but hardly depends on x despite the essential increase in the energy gap.
