Product Description

Product Description

Europium is a metallic element, silvery white
Element description: The first ionization energy is 5.67 electron volts. Can burn into oxides; oxides are approximately white.
Molecular formula: Eu
Molecular weight: 151.964
Color and Appearance: Silver
Stability: easily oxidized in air, should be stored in argon
Europium is an iron-gray metal with a melting point of 822°C, a boiling point of 1597°C and a density of 5.2434 g/cm3; it is the least dense, softest and most volatile element among rare earth elements. Europium is the most active metal among rare earth elements: at room temperature, europium immediately loses its metallic luster in the air and is quickly oxidized into powder; it reacts violently with cold water to generate hydrogen; europium can interact with boron, carbon, sulfur, phosphorus, hydrogen, nitrogen Wait for the reaction. Europium is widely used in the manufacture of reactor control materials and neutron shielding materials.
Application field
It is used as a phosphor for color TVs and has important applications in laser materials and atomic energy industries.
Europium oxide is mostly used in phosphors. Eu3+ is used as an activator for red phosphors, and Eu2+ is used for blue phosphors. Y2O2S:Eu3+ is the best phosphor for luminous efficiency, coating stability, and recovery cost. Coupled with improvements in technologies such as improving luminous efficiency and contrast, it is being widely used.
In recent years, europium oxide has also been used in stimulated emission phosphors for new X-ray medical diagnostic systems. Europium oxide can also be used to make colored lenses and optical filters, used in magnetic bubble storage devices, and can also be used in control materials, shielding materials and structural materials of atomic reactors. Because its atoms can absorb more neutrons than any other element, it is often used as a neutron-absorbing material in atomic reactors. In addition, it can be used as a phosphor for color TV sets, these phosphors emit bright red, and are used to make TV screens; laser materials, etc.
