Lithium fluoride is a chemical compound of lithium and fluorine. It is a white, inorganic, crystalline, ionic, solid salt under standard conditions. It transmits ultraviolet radiation more efficiently than any other substance. Uses include specialized UV optics,[1] and as a means to record gamma and neutron exposure in thermoluminescent dosimeters. Lithium fluoride also has a very high electrical resistance due to its wide band gap.
