Crystal structure and fluoride-ion conductivity of strontium cerium fluoride epitaxial films prepared by topochemical fluorination
Topochemical fluorination of perovskite SrCeO<sub>3</sub> epitaxial thin films using polyvinylidene difluoride was performed at different annealing temperatures (<i>T</i><sub>f</sub>) for 1 h. Fluorite Sr<sub>0.5</sub>Ce<sub>0.5</sub>F<sub>2.5</sub> epitaxial thin films were obtained at <i>T</i><sub>f</sub> > 350 °C, which exhibited fluoride-ion conductivity with an activation energy of 0.61 eV.
