Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.

Zinc sulfide occurs in nature in two crystalline forms, the minerals, wurtzite, and sphalerite. Sulfide ore is principal. The most important use of this compound is as a pigment. As lithopone, a mixture with barium sulfate, it forms a low gloss interior house paint. The pigment, "mineral white" is made by combining zinc sulfide with zinc oxide. Zinc sulfide is incorporated into phosphors to produce luminescence when irradiated with light. it is used in making luminous dials, x-ray and television screens, and fluorescent light. Also, it is used in making white and opaque glass and as a base for color lakes(which consist of an organic pigment with an inorganic carrier).

Catalyst

Fine ZnS powder is an efficient photocatalyst, which produces hydrogen gas from water upon illumination. Sulfur vacancies can be introduced in ZnS during its synthesis; this gradually turns the white-yellowish ZnS into a brown powder and boosts the photocatalytic activity through enhanced light absorption.
