What property does zinc sulfide have?
Zinc sulfide
This inorganic compound has a chemical composition of ZnS. It appears as a powder that is white, off-white or yellow. Zinc Sulfide is stable when in dry air. When in humid air over a period of time or with moisture, it slowly oxidizes to zinc sulfate. It is insoluble in water and soluble in diluted inorganic acids.
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 crystal ZnS as an activater, it will emit different colors after illumination.
What are the applications of zinc sulfide?
The zinc sulfide compound semiconductors are important because they have outstanding physical characteristics, including a large band gap, high refractive indices and high light transmissibility in the visible spectrum. They also offer great potential for optics, electronic and optoelectronic applications.
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-zinc-sulfide caused In 1994 Bhargava reported on the surface passivation properties of nano ZnS:Mn-phosphor, which not only had an external quantum efficiencies of up to 18% at high temperatures but also a fluorescence life of five orders of magnitude shorter. The performance of ZnS has improved dramatically, opening up new possibilities for its use in materials.
Zinc Sulfide: Used as an analytical reagent in paints, paint manufacturing, white and opaque glasses, filling of rubber and plastics, and to prepare phosphor.
