| 中文摘要 | material formulated as ce5.2sm0.8-xprxmo15-(delta) (x=0.08) was prepared by adding small amounts of pr dopant in oxide ce5.2sm0.8-xprxmoo15-delta. structural and electrical properties were investigated by means of x-ray diffraction (xrd), raman spectroscopy, x-ray photoelectron spectroscopy (xps), field emission scanning electron microscopy (fe-sem) and ac impedance spectroscopy. the effect of small amounts of pr on microstructure and electrical conductivity was discussed. it was showed that the material doped with pr has a lot of dents and small openings, which provide channels for oxygen ions, resulting in lower grain boundary and total conductivity activation energy. thus the corresponding grain boundary conductivity and total conductivity of the material were improved notably. the grain boundary conductivity of the material doped with pr is 6.79 x 10(-3) s center dot cm(-1) at 500 degrees c, which is twice as large as that without pr (5.61 x 10(-5) s center dot cm(-1)). |
