N2 - Temperature dependent NMR measurements as well as XAS investigations on La1-xSrxF3-x (x=0.0, 0.01, 0.05, 0.16) have been performed to study the fluorine diffusion in these solid electrolytes and to elucidate the effect that doping with heterovalent SrF2 has on LaF3. A three-stage process of diffusion was observed. Upon increasing temperature, initial ionic exchange begins in the F1 sublattice. At even higher temperatures, dependent upon dopant concentration, ionic exchange between the F1 and F2,3 sublattices takes place. A further increase in temperature eventually leads to exchange over all F- structural positions.
