Sm0.1Ce0.9O1.95 (SDC) films, as promising electrolyte materials, have been successfullyprepared on Al2O3 ceramic substrates by RF magnetron sputtering growth. The relationship betweensputtering parameters and film microstructure was discussed. Scanning electron microscopy (SEM) andx-ray diffraction (XRD) were used to characterize the morphology and crystal structure of the SDC films.The SEM images show that the crystallinity becomes better and better with the increase of sputteringpower from 100W to 300W. X-ray diffraction patterns indicate that the thin SDC electrolyte film on theAl2O3 ceramic substrate grows preferentially along the (111) compact plane with a pure fluorite structurewhen the RF power reaches 300W. After annealing treatment at 600°C and 800°C, respectively, it can beseen that SDC film becomes denser with few pinholes at the annealing temperature of 800°C. Highoxygen ion conductivity (1.46×10-2 Scm-1) of the SDC film was obtained when the RF sputtering powerand annealing temperature were 300W and 800°C, respectively
