Zinc sulfide The chemical formula is ZnS. It is a white or off-white powder. Zinc Sulfide turns darker when exposed to sunlight.

Zinc Sulfide – A Property of Zinc Sulfide

Zinc Sulfide is stable when in dry air. When in humid air over a period of time or in air that contains moisture, the zinc sulfide will oxidize into zinc sulfate. Zinc Sulfide is insoluble in water but soluble in dilute organic acid.
Zinc sulfide, or zinc sulfide, is usually obtained through the reaction of hydrogen sulfide with zinc salt solutions. When a small quantity of Cu,Mn,Ag is added to the ZnS crystals as an activater, they can emit different colours of fluorescence when illuminated. Zinc Sulfide has many uses, including as an analytical reagent for paint, making paint, white and opaque glasses, filling rubber and plastics, and preparing phosphor.

Zinc Sulfide Application:

The zinc sulfide compound semiconductors are gaining attention for their excellent physical properties such as their wide band gaps, high refractive indices, and high levels of light transmission.

Zinc Sulfide exhibits excellent electroluminescence and fluorescence effects. Nano-zinc has a unique effect. It has excellent properties in the areas of magnetism, electricity, optics and mechanics. It is for this reason that research into nano-zincsulfide was sparked in 1994 by Bhargava, who reported on the fluorescence life of nano ZnS:Mn at high temperatures, which has been shortened 5 orders of size. ZnS has a much improved performance that opens up a whole new field of application.

Zinc sulfide may be used for making white pigments and glasses, luminous dust, rubber, paint, plastics etc.
