· GdSe2

GdSe2 is a rare-earth selenide ceramic compound belonging to the lanthanide chalcogenide family, composed of gadolinium and selenium. This material is primarily investigated in research contexts for optical and electronic applications, including potential use in infrared optics, photonic devices, and solid-state lighting systems where rare-earth dopants and wide bandgap semiconductors are advantageous. GdSe2 is notable within the rare-earth ceramics class for its thermal stability and potential mid-infrared transparency, making it an alternative to more conventional oxides in specialized optical and quantum device applications.
