Abstract | In this work, Ce/Mn dual-doped LaAlO3 ceramics have been synthesized via a facile microwave sintering method. From the detailed investigations of Fourier transform infrared spectroscopy, it has been found that Ce/Mn co-doping can dramatically improve the far-infrared emission capability of LaAlO3 ceramics in the range of 8–14 μm. After co-doping of Ce and Mn, Ce4+ ions in polyhedron site (A-site) induce the transformation of Mn4+ to Mn2+ in octahedron site (B-site), which causes the severe lattice distortion of the unit cell and strengthens the vibration intensities of asymmetrical Mn-O-Mn and Mn-O-Al bonds for the promotion of the far-infrared emissivity. Such dual-doped and perovskite-type LaAlO3 ceramics with excellent far-infrared emission shows great potential as a new generation of far-infrared radiation materials for energy conservation applications. |
