Cation‐Framework‐Preserving Oxygen‐Vacancy Engineering for Broadband Infrared Emission in High‐Entropy Spinel Oxides

ABSTRACT 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) 3 O 4 , a high‐entropy spinel oxide (HEO), by vacuum an...
