· JVASP-105984· TbCeO4

TbCeO4 is a rare-earth oxide ceramic compound combining terbium and cerium oxides, belonging to the family of lanthanide-based ceramics. This material is primarily of research and development interest for applications requiring high-temperature stability and radiation resistance, with potential use in nuclear fuel matrix materials, solid-state lighting phosphors, and advanced refractory systems. TbCeO4 is notable in the rare-earth ceramics family for its potential to combine the luminescent properties of terbium with the oxygen-buffering capabilities of cerium, making it an alternative to single rare-earth oxides in specialized high-temperature or radiation-exposed environments.
