Gd2Se3

Gd2Se3 is a rare-earth selenide compound belonging to the family of lanthanide chalcogenides, formed from gadolinium and selenium. This material is primarily investigated in research contexts for optoelectronic and photonic applications, particularly in infrared sensing and imaging systems where rare-earth semiconductors offer unique optical properties unavailable in conventional semiconductors. Engineers consider rare-earth selenides when designing next-generation thermal imaging, mid-infrared detectors, or specialized photonic devices requiring materials with distinct band structures and transparency windows in spectral regions where silicon and germanium are ineffective.
