AsBiO2F

AsBiO2F is an arsenic-bismuth oxide fluoride ceramic compound combining arsenic, bismuth, oxygen, and fluorine elements. This is a research-phase material primarily explored in photonic and optical applications, particularly for infrared transmission windows and nonlinear optical devices where the fluoride component enhances transparency in mid-to-far infrared regions. It represents an emerging class of mixed-anion ceramics (oxyfluorides) that offer potential advantages over conventional oxide ceramics in specialized optics, though it remains largely a laboratory compound with limited commercial deployment compared to established infrared materials like chalcogenide glasses or sapphire.
