“…1 < 420 nm) is associated with the excitation conditions (λ em = 395 nm). The observed changes agree with the concepts of influence of Mn 2+ ions on the PL spectrum of ZnS [9,10,[19][20][21][22].…”

“…When concentration of Mn 2+ increases, the " electronic" mechanism becomes predominant. It is related to electron transitions between the " intrinsic" energy levels of Mn 2+ ions [10]. Only the band of " manganese" luminescence is observed in the spectra of ZnS : Mn 2+ under selective excitation to the absorption bands of Mn 2+ ions (390, 435, 470, 496 and 535 nm) [24].…”

“…At the same time, the radiation of Mn 2+ ions that also can serve as the sensitizers for the manganese luminescence centers [9] is due to the intracenter energy transitions from the first excited state to the ground state. In our opinion, manganese luminescence centers are formed by Mn 2+ ions that do not isovalently substitute zinc ions; these Mn 2+ ions penetrate, as excess ions, into the interstitial and defect positions of the ZnS crystal lattice and, in doing so, form manganese luminescence centers of several types, depending on their nearest environment [10]. The Mn 2+ ions, which isovalently substitute the Zn 2+ ions at the sites of the ZnS crystal lattice, do not form luminescence centers because of the high symmetry of the intracrystal field and the small probability of intracenter radiative transitions.…”
