Abstract
119Sn atoms produced by radioactive decay of 119Sb impurity atoms in the structure of AsxS1 − x and AsxSe1 − x glasses are stabilized in the form of Sn2+ and Sn4+ ions at arsenic sites and correspond to ionized states of the amphoteric two-electron center with negative correlation energy (Sn2+ is an ionized acceptor, and Sn4+ is an ionized donor), whereas the neutral state of the Sn3+ center is unstable. The fraction of Sn4+ states increases with chalcogen content in glass. 119Sn atoms produced by radioactive decay of 119mTe impurity atoms in the structure of AsxS1 − x and AsxSe1 − x glasses are stabilized at chalcogen sites (they are electrically inactive) and arsenic sites, and the fraction of arsenic atoms decreases with the chalcogen content in glass.
