Product Details

1. Product description:

Zinc sulfide is a group II-VI compound semiconductor material composed of sulfur and zinc. The molecular formula is ZnS, the molecular weight is 97.45, the melting point is 1020°C (15MPa), the white crystal, the lattice constant is 0.547nm, the hexagonal crystal type, and the density is 4.08g/cm3. Almost insoluble in water, but soluble in acid. Long-term storage in humid air will convert it into zinc sulfate. The band gap is 3.6eV, which is the widest among group II-VI compound semiconductor materials. Therefore, a blue light-emitting tube can be made. Powdered zinc sulfide is the most important electroluminescent material and light fluorescent material, used to prepare the fluorescent screen of the picture tube, the scoreboard display, etc. It is also a window material and coating material in infrared optical materials. The zinc sulfide used for phosphors is mostly made by solution method, which is characterized by large output and low cost. The high-purity zinc sulfide synthesized directly by the element in the gas phase is needle-like crystals, and is used to prepare high-performance coating materials and single crystal raw materials. High-pressure single crystal furnace and chemical vapor transport (CVD) can be used to grow zinc sulfide single crystals. Zinc sulfide sheets for optical materials can be prepared by hot pressing and CVD methods, which are widely used in window materials for lasers. In recent years, metal-organic chemical vapor deposition methods are mostly used to prepare zinc sulfide film materials. Due to the low growth temperature, the resulting film has good integrity and few defects, and it is easy to prepare heterojunction optoelectronic devices.

White zinc sulfide darkens when exposed to light, and is easily oxidized into zinc sulfate in the air. Zinc sulfide itself or mixed with zinc oxide can be used as white paint pigment. Pure zinc sulfide does not emit light. If a small amount of Chemicalbook manganese, copper, silver is added to zinc sulfide crystals as activators, it can emit different colors of fluorescence after being irradiated with light, which is called phosphor and is used for making Fluorescent screen, luminous paint. Zinc sulfide is also used in tanning, enamel, rubber, and dye industries.
