Bi2O3
semiconductorBismuth oxide (Bi₂O₃) is a semiconducting ceramic compound widely employed in optoelectronic and photocatalytic applications, particularly in visible-light-responsive systems where its narrow bandgap makes it suitable for light absorption and charge generation. In industry, it serves as a key material in photocatalysts for water purification and pollutant degradation, in optical coatings, and as a dopant or active phase in advanced ceramics and thin-film devices. Engineers select Bi₂O₃ over traditional wide-bandgap semiconductors when visible-light sensitivity and relatively high density are advantageous, though its stability and performance typically benefit from structural modification or composite integration to enhance photocatalytic efficiency and reduce recombination losses.
