摘要：
The nanocrystalline ceria thin films doped with yttria of different concentrations were prepared by using the sol-gel dip-coating method. The complex impedance of the films was measured at various temperatures. It is found that the complex impedance spectroscopies of our nanocrystalline ceria-based thin films show only a residual grain boundary arc, and that the total impedance is increased with an increasing Y3+, concentration and is decreased as the operating temperature is raised.
