BaYF₂ is a barium-yttrium fluoride ceramic compound that belongs to the fluoride ceramics family. It is primarily investigated as an optical and photonic material, particularly for applications requiring high transparency in the infrared spectrum and as a host matrix for rare-earth dopants in laser systems. The material is notable for its low phonon energy compared to oxide ceramics, making it valuable for mid-infrared optics and upconversion fluorescence applications where researchers seek alternatives to traditional glasses and oxides with better thermal stability and optical transmission in specific wavelength ranges.
