摘要：

Cerium-fluoride thin films were prepared by using the vacuum thermal evaporation method. At/CeF3/Al (metal-solid electrolyte-metal) sandwich structure was formed on glass substrates, for the study of the AC conduction mechanism. The impedance analysis was performed in the frequency range from 42 Hz to 5 MHz and in the temperature range from 303 to 403 K. The F- ion conduction through the grain and the grain boundary was analyzed. The modulus and the dielectric spectra analyses revealed the non-Debye nature and the distribution of relaxation times in these films.
