“…In order to identify the Ucenters in vitreous arsenic chalcogenides, we advanced the emission Mössbauer spectroscopy on the 119mm Sn( 119m Sn) and 119 Sb( 119m Sn) isotopes, which made it possible to use materials with a tin concentrations of ~4 × 10 19 and 10 14 cm -3 , respectively [8,9]. This paper is con cerned with the identification of the tin Ucenters in lead sulfide PbS by the 119mm Sn( 119m Sn) and 119 Sb( 119m Sn) emission Mössbauer spectroscopy and the discussion of the results obtained in the framework of the model of Udonor center of tin.…”

The valence and coordination states of the impurity tin centers in the lead sulfide crystal lattice were determined by emission Mössbauer spectroscopy. Tin atoms that replace lead atoms are two electron donors with negative correlation energy. The correlation energy U = -0.072 ± 0.004 eV, as well as the posi tions of the first (E V + E 1 = 0.079 ± 0.002 eV) and second (E V + E 2 = 0.151 ± 0.004 eV) ionization energies, were determined (E V is the energy of the top of valence band).
