What is EUROPIUM?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is EUROPIUMwhich has developed particularly rapidly in recent years. Do you know about EUROPIUM?
The official answer:Europium [1] is a metallic element, silvery white, that can be burned into an oxide; The oxide is approximately white. Europium is an iron gray metal with a melting point of 822 °C and a boiling point of 1597 °C, and a density of 5.2434 g/cm³; It is the softest and most volatile element of rare earth elements. [2] Europium is the most reactive metal in rare earth elements: at room temperature, europium immediately loses its metallic luster in the air and is oxidized into a powder; React with cold water to generate hydrogen; Europium can react with boron, carbon, sulfur, phosphorus, hydrogen, nitrogen and so on. Europium is used in the manufacture of reactor control materials and neutron protective materials. Used as a phosphor for color television sets, it has important applications in the europium (Eu) laser materials and atomic energy industry.
Europium is one of the rarest rare earth elements. Its content on Earth is only 1.1 ppm. It is a soft, shiny, steel-gray metal with strong ductility and malleability, which means it can be machined into a variety of shapes. It looks and feels like lead, but heavier.
What’s the application of EUROPIUM?
Used as a phosphor for color television sets, it has important applications in the laser materials and atomic energy industry.
Europium oxide is used in phosphors. Eu3+ is used as an activator for red phosphors and Eu2+ for blue phosphors. Y2O2S:Eu3+ is the best phosphor for luminous efficiency, application stability, recycling cost, etc. Coupled with improvements in technologies such as improving luminous efficiency and contrast, it is being used.
In recent years, europium oxide has also been used in stimulated phosphors for new X-ray medical diagnostic systems [8]. Europium oxide can also be used in the manufacture of tinted lenses and optical filters for magnetic bubble storage devices, as well as in control materials, shielding materials and structural materials for atomic reactors. Because its atoms can absorb more neutrons than any other element, it is often used as a material for absorbing neutrons in atomic reactors. Besides, it can be used as a phosphor for color television sets, which emit a shiny red color and is used to make a TV fluorescent screen; Laser materials, etc.
Rare earth europium complex [9] is a red fluorescent material with high luminescent quantum efficiency of organic compounds and good stability of inorganic compounds, which has good application prospects.
