Zinc sulfide (ZnS) is a chemical compound composed of zinc and sulfur. It occurs in two main crystal forms: the more stable cubic form, also known as zinc blende (or sphalerite), and the hexagonal form known as wurtzite. ZnS is a wide bandgap semiconductor and exhibits properties such as high refractive index, optical transparency in the visible range, and luminescence, which make it suitable for various applications in nanotechnology.
