Abstract

Cobalt-based perovskite oxides, LnBaCo₂O_5+δ (Ln=La to Lu), were investigated as potential variable electrical and thermal radiative materials under solar irradiation. The particular Ln³⁺ dopant has a significant effect on the oxide's phase structure, spectral reflectivity, electrical conductivity, and thermal radiative properties. Stable, cation-ordered oxides with layered lattice structures were obtained with medium-size Ln³⁺ ions. The general features of the electrical and spectral reflective properties of LnBaCo₂O_5+δ (Ln=La, Nd, Sm to Ho) are discussed. It is shown that LnBaCo₂O_5+δ (Ln=Sm to Ho) has a significant insulator–metal transition under solar irradiation, whereas LnBaCo₂O_5+δ (Ln=La, Nd) has a lower infrared emissivity at high temperatures due to the metal-like optical behavior.
