Zinc Sulfide (ZnS)
Zinc sulfide, or ZnS, is an exceptional semiconductor material that usually comes in solid form, ranging in color from white to light yellow. It’s highly valued for its purity and versatility, playing a crucial role in technology across different industries.
This material is essential in applications such as Holographic anti-counterfeiting, and specialized coatings, thanks to its unique characteristics.

Evaporation technique of Zinc Sulfide
Zinc sulfide can be evaporated by electron beam from a molybdenum or tantalum crucible liner. It is usually deposited in a dedicated vacuum chamber because zinc and sulphur have high vapor pressures at low temperatures.
