摘要

Layered SmBaCo2O5+λ with the cation-ordered double perovskite structure were synthesized by the solid-state reaction route and characterized by thermal analysis, X-ray diffraction, infrared spectrum, electrical conductivity and infrared emissivity. The Sm1-xBa xCoO3(SBCO) system shows the different crystal structures with the variation of barium content, which results in the different electrical behavior. The electrical conductivity reaches maximum when x is 0.5 with SmBaCo2O5.54 phase. The infrared absorption occurs at about 600 cm-1 for all the samples which were attributed to Co-O stretching modes. The peak shifted to a lower frequency with the increase of doping level. In addition, the comparison of electrical and emissivity measurements suggested that variation of infrared emissivity is in agreement with the electrical properties.
