Zinc selenide (ZnSe) and zinc sulfide (ZnS) are both binary compounds of zinc and belong to optical materials. They exhibit similarities in certain physical and chemical properties. So, what are the differences between zinc selenide and zinc sulfide? Let's take a look together!
Differences in chemical formulas
The chemical formula of zinc selenide is ZnSe, while the chemical formula of zinc sulfide is ZnS. They are composed of two different elements, zinc and selenium, and zinc and sulfur.
Optical properties of zinc selenide and zinc sulfide
Zinc selenide has a wide optical bandgap, usually larger than zinc sulfide, and higher transmittance in the visible and near-infrared spectral ranges. Zinc selenide is often used as an optical lens, window material, and infrared optical device. In contrast, zinc sulfide has poor transparency, but it still has value in certain specific applications.
Electrical properties of zinc selenide and zinc sulfide
Zinc selenide is a semiconductor material with high electron mobility and low electrical resistivity, while zinc sulfide, although also a semiconductor, has relatively poor electrical properties, which limits its application in certain fields.
Zinc selenide and zinc sulfide in terms of thermal stability
Zinc selenide has good stability at high temperatures and can maintain its structure and performance stability at higher temperatures. However, zinc sulfide is prone to decomposition at high temperatures, leading to a decrease in performance.
There are significant differences between zinc oxide and zinc sulfide in terms of chemical formula, optical properties, electrical properties, thermal stability, preparation methods, and application fields.
The above is an answer to the difference between zinc selenide and zinc sulfide, hoping to be helpful to you. If you have any questions, please feel free to consult online or leave a message.
