High-entropy materials are a new field of research involving entropy stabilized single-phase solid solutions with at least five equal molar elements. High-entropy sesquioxide transparent ceramics in equal molar and nearly equal molar were successfully fabricated by vacuum sintering to reach a relative density of 99.98%. Their thermal, optical and luminescence properties were investigated and discussed. The highest in-line transmittance in visible and IR range is nearly 80%. By adding luminescence ions, the high-entropy ceramics show an up-conversion emission. Such a high-entropy transparent ceramics could be realized in multiple sesquioxide composition systems. By incorporating the high-entropy principle with transparent ceramics will largely broaden the family of optical ceramics.
