Abstract
- Ce<subscript>1-x</subscript>Sm<subscript>x</subscript>O<subscript>2-δ</subscript> (x = 0.0, 0.1, 0.2, 0.3) samples were prepared by sucrose and pectin–assisted auto combustion method. The phase identification, morphology, spectroscopic properties, and electrical properties of the samples are studied by XRD, FESEM, Raman spectrometer, and impedance spectroscopy. Rietveld refinement was carried on XRD samples for structural properties. Samples showed a single phase with the cubic fluorite structure. The average crystallite size was in the range of 10–17 nm. The sample Ce<subscript>0.8</subscript>Sm<subscript>0.2</subscript>O<subscript>2−δ</subscript> exhibits improved conductivity with low activation energy in comparison with pure ceria.
