Abstract

Mössbauer Spectroscopy, the recoil-free resonant absorption of γ-rays, is really suitable for the study of local electronic structure. Its hyperfine parameters, the isomer shift δ and quadrupole splitting ∆, respectively proportional to the s electronic density at the nucleus and to the electric field gradient, allow one to characterize the oxidation state and coordination of the probed element. Several examples illustrate the capabilities of this powerful technique for different elements (Sn, Fe, Sb) in tin oxide glasses as electrode materials for Li-ion batteries, iron phosphate glasses used for the treatment of inorganic waste and antimony chalcogenide glasses for optoelectronic applications..
