· Y2 S2 F2

Y2S2F2 is a rare-earth fluorosulfide semiconductor compound containing yttrium, sulfur, and fluorine. This material belongs to an emerging class of mixed-anion semiconductors currently under investigation for optoelectronic and photonic applications, where the combination of fluoride and sulfide anions offers potential advantages in bandgap engineering and optical transparency. While not yet commercially widespread, materials in this family are studied for their potential in UV-to-visible light emission, scintillation detection, and as alternatives to conventional II-VI semiconductors in specialized photonic devices.
