· Ca1 Ho2 Se4

Ca1Ho2Se4 is a rare-earth chalcogenide semiconductor compound combining calcium, holmium, and selenium in a ternary phase. This material belongs to the family of lanthanide chalcogenides, which are primarily investigated in research settings for optoelectronic and photonic applications due to their tunable bandgaps and rare-earth luminescent properties. Industrial adoption remains limited; the compound is of interest to materials researchers exploring next-generation light-emitting devices, infrared detectors, and specialized photonic components where rare-earth dopants provide wavelength tunability and enhanced performance beyond conventional binary semiconductors.
