· JVASP-21017· TbPS4

TbPS4 is a terbium phosphorus sulfide ceramic compound that combines rare-earth and chalcogenide chemistries. This material belongs to the family of ternary metal phosphide sulfides, which remain largely in the research phase but show promise for optoelectronic and photocatalytic applications. As an experimental compound, TbPS4 is of interest to materials scientists exploring rare-earth ceramics for next-generation semiconductors, photon conversion devices, and potentially solid-state lighting or energy-harvesting systems where the rare-earth dopant can provide unique electronic and optical properties.
