Lanthanum Fluoride Crystal Substrates Applications

There are very few high-index materials in the far UV. LaF3 is one. Lanthanum Fluoride Crystal Substrate is also a component of multimetal fluoride glasses such as ZBLAN. It is also used (with europium fluoride, EuF2) in fluoride selective electrodes. Lanthanum Fluoride Crystal Substrate can be used for the preparation of modern medical image display technol.
