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 gradually 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 crystalline ZnS is activated with a small quantity of Cu,Mn,Ag, the ZnS can emit different fluorescence colors when illuminated. Zinc Sulfide has many uses, including as an analytical reagent for paints, opaque and white glass, rubber filling, plastic and for phosphor preparation.

Zinc Sulfide Application:

The zinc sulfide compound semiconductors are a very important material. They have been gaining attention for their excellent physical properties such as a large band gap, refracting index, and light transmittance.

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, mechanicals, and catalysis. It is for this reason that research into nano-zincsulfide was a success. In 1994, Bhargava published a report stating that surface passivation nano-ZnS phosphors had an external quantum efficiencies of up to 18% when heated at high temperatures. They also had shortened fluorescence lives by 5 orders and also emitted light. ZnS has a much improved performance that opens up new applications for it.

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