Infrared Emittance and Electrical Properties of Ce⁴⁺ Doped Sm_0.5Sr_0.5CoO₃ Ceramics

Abstract:

A series of Sm_0.5Sr_0.5CoO₃-CeO₂ ceramics formed by solid state-reaction method have been systematically investigated. The effects of doping the Sm site of Sm_0.5Sr_0.5CoO₃ with Ce⁴⁺ on the structural, spectral reflectance, and thermal radiation properties were also explored. The modification of the initial phase takes place can be ascribed to the dissolution of Ce from initial CeO₂ into the perovskite structure. The conductivity behavior depends critically on the Ce doping level, as was demonstrated that the recombination of holes (from Sm_0.5Sr_0.5CoO₃) and electrons (from ceria ion) could decrease electrical conductivity. Sm_0.5Sr_0.5CoO₃-CeO₂ ceramics showed continuously adjustable conductivity and infrared emittance, opening up possible applications in solar thermal conversion or thermosensitive conductivity.
