摘要

Perovskite-type complex oxide Sm_0.5Sr_0.5CoO_3-δ(SSC5) powders was prepared by sol-gel method with citric acid as chelate, and subsequently characterized by TG-DSC, XRD, SEM, XPS and UVPC. The results show that the SSC5 powders were formed at 1 200℃ for 6 h, the grain size was approximately 1 μm. The states of cobalt have been changed into Co³⁺ and Co⁴⁺ as a result of the Sr²⁺ substitution for Sm³⁺, and a lot of adsorption oxygen species appear on the surface of SSC5. The solar absorptance (α_S) and thermal emittance (ε_T) of SSC5 are 0.71 and 0.19, showing good spectral selectivity.
