What are the uses of zinc sulfide?

wallpapers News 2021-12-23
Zinc sulfide is an important semiconductor material due to its fluorescence, phosphorescence, and infrared transparency. Zinc sulfide is widely used in many fields such as luminescence, sensing, infrared window materials, and photocatalysis. Doped zinc sulfide is a widely used luminescent material, such as phosphors (ZnS: Cu, Al), electroluminescent materials (ZnS: Mn), photoluminescent materials (ZnS: Cu, Er), and so on. Zinc sulfide is used as a white inorganic pigment and fluorescent pigment, which can produce beautiful brilliance. It has high near-ultraviolet reflectance, low abrasiveness and oil absorption, excellent rheology, is stable to light and heat and is easy to react to organic pigments and polymers. Will not produce harmful catalysis.
Zinc sulfide can be used in coatings, printing inks, plastics, thermoplastic and thermosetting resins, resin elastomers, synthetic fibers, paper, lubricants, paint, glass, rubber, etc. If zinc sulfide contains trace amounts of copper and silver ions, it can produce fluorescent colors. This performance can be used for components of televisions, oscilloscopes and X-ray devices, and various signs. 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-shaped crystals, and is used to prepare high-performance coating materials and single-crystal raw materials.
A 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.
