Lanthanum Trifluoride (LaF3) Powder

Lanthanum trifluoride (LaF₃) is an ionic compound of rare earth-metal lanthanum and fluoride. The crystal structure of LaF₃ belongs to the hexagonal crystal system. Similar to other rare-earth materials LaF₃ powders improve the mechanical strength of composites. Thus, LaF₃ powder can significantly strengthen the load-bearing capacity and wear resistance of the lubricating coatings. Furthermore, it is an eco-friendly and inexpensive filler material in comparison to gold and silver nanoparticles. LaF₃ nanoparticles also show notable optical properties and high ionic conductivity at ambient temperatures. LaF₃ nanoparticles can show strong near-infrared (NIR) and up-conversion fluorescence emission under NIR excitation. Ionic conductivity of LaF₃ is utilized in chemical sensors for sensing fluoride, oxygen and carbon monoxide because of its high chemical stability. The optical properties of LaF₃ are utilized in fiber optics, fluorescent lamps, and radiation applications. Other promising applications of LaF₃ are lighting, displays, biological labels, bio probes, and optical amplifiers.
