Abstract

With the evolution of infrared detection technology and the increasingly complex combat environment, it is vital to develop advanced infrared stealth technology. In this study, Ba²⁺-doped LaCoO₃ bulks were prepared via solid phase method and the Ba²⁺-doping effect on infrared radiation ability was investigated. The results showed that the infrared emissivity of Ba²⁺-doped LaCoO₃ was related to the electronic structure and the lattice transformation. The average infrared emissivity of LaCoO₃ was 0.89 in the 3–5 μm band, 0.91 in the 8–14 μm band, and 0.90 in the 3–14 μm band. Due to the overlap between Co-3d and O-2p electron orbits and the lattice transformation, La_0.5Ba_0.5CoO₃ bulk had the lowest average infrared emissivity with 0.39 in the 3–5 μm band, 0.27 in the 8–14 μm band, and 0.31 in the 3–14 μm band. La_0.5Ba_0.5CoO₃ exhibits low infrared emissivity, showing potential as a future infrared emission material in the 3–14 μm band.
