CdSe2 is a cadmium selenide ceramic compound belonging to the II-VI semiconductor family, characterized by its crystalline structure and direct bandgap properties. This material is primarily used in optoelectronic and photonic applications, including quantum dots for display technologies, photodetectors, and solar cells, where its tunable optical properties enable precise control over light emission and absorption wavelengths. CdSe2 is notable for its strong photoluminescence efficiency and quantum confinement effects in nanocrystalline form, making it valuable for advanced imaging and sensing systems, though environmental and health considerations regarding cadmium content have driven increased research into alternative lead-free semiconductors in many applications.
