摘要

采用高温固相法制备了LaCoO

和La

0.75

0.25

0.5

材料，通过XRD、SEM、XPS和IR等检测手段对材料进行表征分析，并运用计算机模拟软件CASTEP计算了材料的能带结构和光学性质。基于以上结果研究了钴酸镧系列材料的红外辐射性能，并分析了提高红外发射率的物理机制。结果表明：Ca-Fe共掺杂后试样的晶体结构由纯物质的菱方结构转变为立方结构，试样在2.5~5 m波段的发射率值从0.83提高到0.9，发射率提高的机理在于：Fe

和Co

小极化子的形成增强了材料对自由载流子吸收；Co原子的3d轨道与Fe原子的3d轨道杂化在费米能级处形成杂质能级，促进了受激发电子的跃迁；Ca-Fe掺杂在一定程度上破坏了晶格的对称性，促进了晶格振动吸收，提高了材料的红外发射率。钴酸镧体系材料在中红外波段的红外发射性能优异，可在高温窑炉工业得以应用。

materials were prepared by solid-state method

which were characterized by using the detection methods

such as XRD

SEM

XPS and IR. The electronic structures and optical properties of the samples were calculated by using the computer simulation software CASTEP. Based on the above results

the infrared radiation properties of the studied materials were investigated

further the improving mechanism of infrared emissive properties was analyzed. The results show that the crystal structure is changed from the rhombohedral structure for the non-doped sample to the cubic structure for Ca-Fe co-doped sample

and the emissivity in the 2.5-5 m range was increased from 0.83 for the non-doped sample to 0.9 for Ca-Fe co-doped sample. The increasing mechanism of the emissivity is considered as the following aspects:Fe

and Co

mini-polarons form

which enhance the free carrier absorption. The defect levels appear at the Fermi level by the 3d orbital hybridization of Co atom and Fe atom

which promote the transition of excited electrons. Ca-Fe co-doping undermines the lattice symmetry in a certain degree

promoting the lattice vibration absorption and improving the infrared emissivity of the material. The lanthanum cobalt oxide system material has excellent emission performance in the mid-infrared band and can be applied in the high-temperature furnace industry.
