· JVASP-107019· YbY2Se4

YbY2Se4 is a mixed rare-earth selenide ceramic compound belonging to the family of rare-earth chalcogenides. This material is primarily of research interest rather than established in widespread industrial production, studied for its potential in optoelectronic and thermal management applications due to the unique electronic properties imparted by ytterbium and yttrium co-doping. The compound's notable characteristics make it a candidate for specialized applications where rare-earth ceramics provide advantages in thermal stability, radiation resistance, or specific optical properties compared to conventional ceramics or semiconductors.
