Abstract Dissipation of heat efficiently from a hot object via radiation while minimizing the inward heat conduction is the key requirement of radiation thermal protection. In this study, a Ca-Cr co-doped Y3NbO7 coating with lamellar porous structure is fabricated, which shows an ultra-low thermal conductivity (<0.7 W m−1 K−1) and near-unity emissivity (>0.9) across a broad wavelength range of ≈1–24 µm.
