Cation-Framework-Preserving Oxygen-Vacancy Engineering for Broadband Infrared Emission in High-Entropy Spinel Oxides.
High-temperature radiative ceramics require broadband infrared emission and stable structures, but the defects that enhance emission can also weaken oxide lattices. Here, we regulate oxygen vacancies in (MnCrFeNiCu)3O4, a high-entropy spinel oxide (HEO), by vacuum annealing without changing the nominal cation compositi...
