中文摘要	ce6-xdyxmoo15-delta (0.0 <= x <= 1.8) were synthesized by modified sol-gel method. structural and electrical properties were investigated by means of x-ray diffraction (xrd), raman, x-ray photoelectron spectroscopy (xps) and electrochemical impedance spectroscopy (eis). the xrd patterns showed that the materials were single phase with a cubic fluorite structure. impedance spectroscopy measurement in the temperature range between 350 degrees c and 800 degrees c indicated a sharp increase in conductivity for the system containing small amount of dy2o3. the ce5.6dy0.4moo15-delta detected to be the best conducting phase with the highest conductivity (sigma(t) = 8.93 x 10(-3) s cm(-1)) is higher than that of ce5.6sm0.4moo15-delta (sigma(t) = 2.93 x 10(-3) s cm(-1)) at 800 degrees c, and the corresponding activation energy of ce5.6dy0.4moo15-delta (0.994 ev) is lower than that of ce5.6sm0.4moo15-delta (1.002 ev).
