“…It is noteworthy that the lines corresponding to the divalent and tetravalent states of tin in the 119 Sb( 119m Sn) Mössbauer spectra converged with increasing the temperature (from 80 to 295 K) for the case of lead selenide [5]. The latter fact was interpreted by Bordovsky et al [5] as the conse quence of two electron exchange between different charge states of tin. However, it can be seen from Fig.…”

It has been shown using the Mössbauer emission spectroscopy for isotope 119 Sn that impurity tin atoms formed after the radioactive decay of 119 Sb atoms in vitreous arsenic sulfide and selenide are localized in arsenic sites and play the role of two electron centers with negative correlation energy. The most of daugh ter 119m Sn atoms formed after the radioactive decay of the 119m Te atoms in glasses are arranged in chalcogen sites; they are electrically inactive. Considerable recoil energy of daughter atoms in the case of decay of 119m Te leads to the appearance of 119m Sn atoms shifted from chalcogen sites.

“…Bishop, Strom, and Taylor [5][6][7] examined optically induced localized paramag netic states in chalcogenide glassy semiconductors by electron spin resonance and explained why negative U centers could not be observed while using electron spin resonance standard registration methods. Nega tive U centers of tin were detected for the first time by the method of 119 Sn Mössbauer spectroscopy in chal cogenide glasses [8][9][10]. The existence of two valence states Sn 2+ and Sn 4+ for tin, differing by 2e, may be the reason for formation negative U centers in the glass by tin.…”
