· Ba3Tb2(PS4)4

Ba3Tb2(PS4)4 is a rare-earth thiophosphate semiconductor compound combining barium, terbium, phosphorus, and sulfur in a fixed stoichiometric structure. This is a research-phase material studied primarily for its optical and electronic properties within the broader family of rare-earth phosphate and thiophosphate compounds, which show promise for photoluminescence, scintillation, and solid-state lighting applications where lanthanide-doped hosts are valuable. The material's potential lies in leveraging terbium's strong green photoemission and the thiophosphate framework's tunable bandgap for emerging optoelectronic devices, though industrial adoption remains limited pending further development of synthesis scalability and device integration pathways.
