Figure 1

(a) PXRD pattern obtained for the as-prepared, Ba0.5Sr0.5Ce0.6Zr0.2Gd0.1Y0.1O3−δ (perovskite I) revealing the formation of cubic perovskite structure with a very small impurity peak near 2θ values of 30°, (b) TEM image of perovskite I (c) HR-TEM (d) SAED pattern of perovskite I with their corresponding crystal planes indexed again suggesting the formation of single phase and (e) SEM image of perovskite I showing grains in the range of 2–3 μ and revealing the dense nature of the pellet.
