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 to off-white. Zinc Sulfide is stable when in dry air. When in humid air over a period of time or with moisture, it gradually oxidizes to zinc sulfate. It is insoluble when mixed with water and soluble when mixed with dilute 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 (optics), mechanics (mechanics) and catalysis. It is for this reason that research into nano-zinc-sulfide caused in 1994, Bhargava to report that the surface passivation on nano ZnS:Mn has a quantum efficiency external of up 18% when heated at high temperatures. The performance of ZnS has improved dramatically, opening up new possibilities for its use in materials.
Zinc Sulfide: Used as a paint, paintmaking, opaque and white glass, filling of rubber and plastic, and to prepare phosphor.
