Zinc Sulfide
Zinc sulfide (ZnS) is an inorganic compound composed of zinc and sulfur. It typically appears as a white or pale yellow crystalline solid and is known for its luminescent and optical properties.

Zinc sulfide (ZnS) is widely used in thin film coatings due to its unique optical and luminescent properties. It is valued for its high transparency across a broad range of wavelengths, high refractive index, and stability, making it an ideal choice for various optical and photonic applications:

1. Infrared (IR) Coatings: ZnS thin films are commonly used as IR-transparent coatings for windows and lenses in infrared imaging systems, night vision devices, and IR sensors due to their excellent transmission in the mid-IR range.
2. Optical Coatings: Anti-Reflective (AR) coatings and High-Refractive Index Layers.
3. Protective Coatings.
4. Laser and Photonic Applications:Used in thin films for laser optics and photonic devices, providing high damage thresholds and excellent optical performance under high-intensity laser light.
5. Electroluminescent Devices: ZnS is a primary material in thin film electroluminescent displays and devices. Doping ZnS with activator elements like copper or manganese creates phosphorescent films for use in display panels and lighting.

Zinc sulfide’s high transparency, strong luminescent properties, and versatility in both visible and infrared applications make it a preferred material for thin film coatings in optical devices, IR systems, and display technologies.
