Europium Fluoride

Europium fluoride powder is a white crystalline, chemically stable, water-insoluble but acid-soluble rare earth metal compound with high refractive index, which is widely used in the fields of luminescent materials, optical coatings, glass ceramics, catalysts and scientific research.

Characteristic

Chemical formula: EuF3

Molecular weight: 208.96 g/mol

Density: 6.5 g/cm³ (also shown as 6.495 g/cm³)

Melting point: 1390°C

Boiling point: 2280°C

Magnetism: europium ion (Eu³⁺) has unpaired electrons, so europium fluoride powder has a certain paramagnetism

Optical properties: Europium fluoride powder has unique optical properties and is a good luminescent material. It can emit bright red light under the irradiation of excitation sources such as ultraviolet rays, so it is used as a red phosphor in display technologies such as cathode ray tubes and plasma screen displays.

Applications

Light emitting materials: widely used in the production of red phosphors for cathode ray tubes and plasma screen displays, etc. It plays an important role in presenting bright red colour;

Optical coatings: it can be used to make optical coatings, using its higher refractive index to change the optical properties of the material, to improve the efficiency of light transmission and to reduce reflections, and is applied to optical devices and components such as lenses, mirrors and windows;

Glass and ceramics: added to glass and ceramics as dopants to give the materials special optical properties, which can be used to make optical fibres, laser materials, fluorescent materials, etc;

Catalysts: they can be applied as catalysts in certain specific chemical reactions, especially in organic synthesis reactions, although their applications in catalysis are relatively few, they still have certain research value;

Nuclear Reactor: Used as neutron absorber in nuclear reactors, it can control the rate of nuclear reaction by slowing down the speed of neutrons to achieve the regulation of nuclear reaction;

Scientific research: Europium fluoride powder is often used for research and development in scientific research fields such as chemistry, material science, solid state physics, etc. Its unique properties are of great significance in understanding the behaviour of materials at the atomic and molecular levels.
