Er2 S4
semiconductor· Er2 S4
Er₂S₄ is a rare-earth sulfide semiconductor compound containing erbium, belonging to the family of lanthanide chalcogenides. This material is primarily of research interest rather than widespread industrial use, investigated for its potential in infrared optics, photonics, and solid-state lighting applications due to erbium's characteristic emission wavelengths in the near-infrared region.
