Neodymium fluoride (also known as neodymium trifluoride) is a chemical compound with the formula NdF3. It is a rare earth fluoride and a white solid material with a cubic crystal structure. Neodymium fluoride is used as a material for making phosphors for use in cathode ray tubes and fluorescent lamps, as a dopant in semiconductor devices, and as a catalyst. It is also used in the production of specialty glasses and as a component of laser materials.

Application

Neodymium fluoride is mainly used for glass, crystal and capacitors, and is the main raw material for making Neodymium Metal and alloys. Neodymium has a strong absorption band centered at 580 nm, which is very close to the human eye's maximum level of sensitivity making it useful in protective lenses for welding goggles. It is also used in CRT displays to enhance contrast between reds and greens. It is highly valued in glass manufacturing for its attractive purple coloring to glass.
