Erbium fluoride is an important material for erbium-doped fiber amplifiers, which can effectively amplify fiber-optic TV signals and ensure stable video transmission. This is widely used in cable TV to provide customers with a better viewing experience.
Adding erbium fluoride to rare earth permanent magnet materials (NdFeB permanent magnet materials) can adjust the crystal structure and magnetism of the materials, and improve the coercive force, remanence and magnetic energy product of the permanent magnet materials, making the permanent magnet materials have better performance in headphones.
Erbium fluoride can be used as a doping material in the preparation of phosphors. These phosphors have high luminous efficiency and are used in LED lights and displays to improve their brightness and color performance.
Other applications: Erbium fluoride is used to manufacture special optical glass. Adding erbium fluoride to optical glass can change the optical properties of the glass, making the optical glass have a higher refractive index. It is also used in certain special processes in semiconductor manufacturing, such as ion implantation and etching.
Q: Can you provide a small amount of erbium fluoride sample?A: We can provide about 10g of sample.
Q: How to transport the goods?A: We have sea, land and air transportation, but mainly sea transportation.
Q: What is the role of optical coating made of erbium fluoride as raw material?A: Optical coating made of erbium fluoride as raw material has the functions of anti-reflection, light filtering, anti-reflection and protection, and improves optical performance and component life.
Q: What is the specific role of erbium fluoride in permanent magnetic materials?A: It has the functions of optimizing crystal structure, enhancing magnetic interaction and improving magnetic stability.
