Applications

Infrared Optical Coatings

With the rapid development of infrared technology and materials in emerging research and application fields, there is an increasing demand for stable, high-quality thin films in the infrared region. Yttrium Fluoride (YF?) is widely used in infrared applications due to its excellent optical properties. In particular, its wide bandgap ensures high transmittance across a broad spectral range from ultraviolet to infrared. Therefore, YF? has become the preferred low-refractive-index material for interference filters and infrared optical coating components.

Solid-State Batteries

Yttrium Fluoride can be used as an additive for solid-state electrolytes or as an interfacial modification layer to enhance the performance of solid-state batteries. Its key functions include:

Improving interfacial contact between the solid electrolyte and electrodes, reducing interfacial resistance;

Suppressing lithium dendrite growth, thereby improving cycling stability;

Widening the electrochemical stability window and enhancing high-voltage tolerance.

These advantages make YF? a promising material for next-generation high-safety, high-energy-density solid-state batteries.
