INFO
Zinc sulfide, ZnS
Zinc sulfide (ZnS) is a semiconducting material that exhibits either a sphalerite (cubic) or wurtzite (hexagonal) crystal structure. It has a direct bandgap of around 3.68 eV for the cubic form and 3.91 eV for the hexagonal form. Due to its luminescent properties, ZnS has been extensively used in applications like electroluminescent panels, X-ray screens, and phosphorescent materials. Doped ZnS, especially with copper or silver, can produce phosphorescent materials widely used in various displays. ZnS is also employed as a host matrix in many quantum dot applications. Additionally, its infrared transmission capability makes it valuable for infrared optics, and it's frequently used in infrared windows and lenses.Other names
