ZINC SULPHIDE

The most common use of ZnS is as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative      During exposure to long wavelength (366 nm) UV light, the zinc sulfide is found to fluoresce and phosphoresce with impressive intensity and vibrant color. After turning the UV light "off" we see the evidence of phosphorescence emission from the zinc sulfide in the form of an "eerie green" glow
