EuSe is a rare-earth chalcogenide semiconductor compound composed of europium and selenium, belonging to the family of lanthanide selenides used primarily in research and specialized optoelectronic applications. This material is of particular interest in infrared optics, magnetooptical devices, and solid-state physics research due to europium's unique magnetic and luminescent properties combined with selenium's semiconducting characteristics. While not widely deployed in mainstream commercial products, EuSe and related rare-earth chalcogenides are pursued by researchers for potential applications in mid-infrared detectors, magneto-optic modulators, and fundamental studies of magnetic semiconductors where alternative materials like IV-VI compounds (PbTe, PbSe) or conventional III-V semiconductors are unsuitable.
