Abstract

We show that the variation of the structural unit in tellurite glasses is due to the charge transfer from modifier atoms to TeO6 octahedra with use of first-principles molecular orbital calculations. Orbital overlap population analysis reveals that the transferred electrons to the Te- O antibonding orbital cause breaking Te-O bonds and lead to reducing the coordination number of the Te atom.
