· JVASP-44293· TbNbO4

TbNbO4 is a rare-earth niobate ceramic compound combining terbium and niobium oxides, belonging to the family of complex oxide ceramics used in high-performance applications. This material is primarily investigated for photocatalytic, optical, and electronic applications due to the unique properties imparted by the rare-earth terbium cation, including potential photoluminescence and catalytic activity. TbNbO4 represents an experimental-to-emerging material in the research domain rather than a commodity ceramic, with potential advantages over conventional niobates in energy conversion, environmental remediation, and specialized optical devices where rare-earth dopants provide enhanced functionality.
