Zinc sulfide It is an organic compound with the chemical formula ZnS. It appears white-to-off-white powder or light yellow. Zinc sulfuride turns darker when exposed light is applied.

The Property of Zinc Sulfide –

Zinc sulfuride is stable when dry. If it’s left in moist conditions for long periods of time, or if there’s moisture in the air, it can slowly oxidize and become zinc sulfate. Zinc sulfuride dissolves in dilute inorganic acids, is easily soluble by alkali and is irritating in zinc sulfide.
Zinc sulfuride is usually obtained through the combination of hydrogen sulfide, zinc salt solution. A small amount of Cu Mn, Ag can be added to the ZnS crystal structure as an activator. It will then emit different colors when illuminated. Zinc sulfuride is useful for paint preparation, analysis, painting, opaque and white glass filling, rubber, plastic and as an analytical reagent.

Zinc Sulfide Application:

Two and six important compound semiconductors zinc sulfide have been attracting a great deal of attention. Not only are they important because of their excellent physical characteristics, like wide band gap and high refractive index and high light transmission in the visible spectrum, but also because of their huge potential to be used for optics, electronics, and optoelectronic device.

Zinc sulfuride is a good choice for electroluminescence as well as fluorescence. A unique photoelectric effect is possible with nano-zinc. This sulfide has outstanding properties in electricity, magnetism optics mechanics and catalysis. Bhargava’s 1994 report on the nano-zinc-sulfide surface passivation showed that it not only had an external quantum efficacy of 18% at high temperatures, but also had a fluorescence lifespan of five orders of magnitude shorter and also emits light. It has a dramatically improved performance, opening up new avenues for ZnS application in materials.

Zinc sulfuride is used for making white pigments such as glass and rubber. It can also be used to produce luminous paints, rubber, plastics, and rubber.
