Abstract
The Ge1 − x − y Sn y Te x vitreous alloys are studied using 119Sn Mössbauer spectroscopy. It is found that the quadruply charged tin ions substituting for germanium in the vitreous alloys under investigation forms an sp 3 system of chemical bonds, whereas the doubly charged tin ions substituting for tellurium exhibit a metallic character of bonds with tellurium atoms in its own local environment.
