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 (YF₃) 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, YF₃ 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 YF₃ a promising material for next-generation high-safety, high-energy-density solid-state batteries.
