Zinc sulfide (ZnS) is a chemically inert material with high purity, insoluble in water, moderate density and easy processing, which is widely used in the manufacture of infrared window, fairing and infrared optical elements. Like zinc selenide (ZnSe) materials, ordinary infrared grade zinc sulfide (ZnS) is also a material with good refractive index uniformity and consistency, and has good image transmission performance. The material also has a high transmittance in the mid-infrared band, but absorption and scattering are enhanced as the wavelength becomes shorter. Compared with zinc selenide (ZnSe), ordinary infrared grade zinc sulfide (ZnS) has low price, high hardness, twice the fracture strength of zinc selenide (ZnSe), and strong ability to resist harsh environment.

High purity industrial zinc sulfide (purity in 95% ~ 98%) powder is a non-toxic, harmless, safe and environmentally friendly green products, with non-toxic and harmless, white pigment blue phase, low wear and other characteristics, is a high-grade anti-wear agent, additives, colorants, heavy metal ion complexing agent and passivating agent. Widely used in the automotive industry, long glass fiber reinforced composite materials, brake pad friction materials, high-grade water-based coatings, automotive paint and other industries, environmental protection and purification effect, is a wide range of functional civil basic materials.

As an important two – and six-compound semiconductor, zinc sulfide nanomaterials have attracted great attention not only for their excellent physical properties such as band gap width, high refractive index, and high transmittance in the visible range, but also for their great potential applications in optical, electronic and optoelectronic devices. Zinc sulfide has excellent fluorescence effect and electroluminescence function, nano-zinc sulfide has a unique photoelectric effect, showing many excellent properties in the fields of electricity, magnetism, optics, mechanics and catalysis, so the research of nano-zinc sulfide has attracted more attention, especially in 1994 Bhargava reported the surface passivation treatment of nano-ZNS: Mn phosphor not only has an external quantum efficiency of up to 18% at high temperature, its fluorescence lifetime is shortened by 5 orders of magnitude, and the luminous performance has a great change, which opens up a new way for the application of ZnS in materials. Can be used to make white pigment and glass, luminous powder, rubber, plastic, luminous paint and so on.
