Rezumat

Luminescent properties of nickel-doped ZnSe crystals with various impurity concentrations are investigated. The concentration of Ni2+ ions in ZnSe crystals has been varied from 0.001 to 0.5 at.%. Photoluminescent studies have confirmed the incorporation of Ni into ZnSe crystals. It is established that Ni forms multicharge (1+, 2+, 3+) acceptor centres in ZnSe, which are the quenching centres for visible and infrared photoluminescence. The emission band with maximum at 2612-2630 nm in infrared spectra of ZnSe:Ni crystals is attributed to 3T2(3F) → 3T1(3F) intrashell transitions within Ni2+ions.
