· Na8 P4 Se12

Na8P4Se12 is a mixed-anion semiconductor compound combining sodium, phosphorus, and selenium in a single crystalline phase. This material belongs to the family of alkali metal chalcogenophosphates and is primarily investigated in research contexts for solid-state ionics and optoelectronic device applications. Its potential utility stems from ionic conductivity pathways and semiconductor bandgap characteristics that make it a candidate for next-generation solid electrolytes and photovoltaic or photocatalytic devices, though practical industrial adoption remains limited.
