Lithium Fluoride

Lithium fluoride is used as a low-refractive index material in multilayer optical coatings, particularly for UV and VUV applications due to its high transparency in those ranges.

LiF is frequently used as an evaporation material for the deposition of thin films in organic light-emitting diodes (OLEDs) to enhance electron injection.

Used as an additive or precursor in the formulation of lithium-ion battery electrolytes to improve the formation of the solid electrolyte interphase (SEI) layer.

LiF targets are utilized in sputtering processes to create thin dielectric layers or protective coatings in microelectronic and optical devices.
