· Bi4 P4 O16

Bi₄P₄O₁₆ is an inorganic phosphate semiconductor compound containing bismuth, phosphorus, and oxygen. This material belongs to the family of metal phosphate semiconductors and is primarily investigated in research contexts for photocatalytic and optoelectronic applications due to bismuth's strong visible-light absorption characteristics. While not yet widely adopted in mainstream industrial production, bismuth phosphates show promise as alternatives to conventional semiconductors in applications requiring earth-abundant, non-toxic materials with tunable bandgaps.
