N2 - 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, La0.5Ba0.5CoO3 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. La0.5Ba0.5CoO3 exhibits low infrared emissivity, showing potential as a future infrared emission material in the 3–14 μm band.
