  • Applications

    Zinc Sulfide (CAS 1314-98-3) is primarily used as a phosphor and luminescent material in display and lighting technologies, including ZnS-based phosphors doped with species such as Cu or Ag for classic glow displays and optical coatings. It serves as a scintillator/phosphor in alpha particle detectors and smoke detectors when formulated as ZnS:Ag, converting radiation into visible light. The material is also used as a glow-in-the-dark pigment in toys, safety signs, and other items that emit light after excitation by UV or ambient light. In optics, high-purity ZnS is employed as an infrared window material for certain imaging systems and infrared laser components. Additionally, ZnS is used in coatings and inks as a specialty luminescent pigment.
