Europium-doped plastic has been used as a laser material. 3 Chemical and Physical Properties Expand this section. Europium is used in the form of its salts as coatings for cathode ray tubes and in the form of its organic derivatives as shift reagents in NMR spectroscopy.
The primary use of europium is in red phosphors in optical displays and TV screens that use cathode-ray tubes and in glass for fluorescent lamps.
When both valencies are combined a white light is produced which is used in compact fluorescent bulbs. Uses. 2 Names and Identifiers Expand this section.
4 Related Records Expand this section. Europium fluorescence are used to interrogate in drug discovery screen for bimolecular interaction. Europium oxide (europia) is widely used as a doping agent in phosphors in television sets and computer monitors: valency three europium produces a red radiance and valency two europium produces a blue radiance. The pure metal is silvery, but after even a short exposure to air it becomes dull, because it readily Europium oxide (Eu 2 O 3), one of europium's compounds, is widely used as a red phosphor in television sets and as an activator for yttrium-based phosphors. Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light. Additionally, europium is used as a dopant in glasses used for lasers and other optoelectronic applications, and has some specialized research applications. Define europium. Uses of europium. Laser material is one byproduct of europium-doped plastic. Color TV screens contain between 0.5 and 1 g of europium. Jefferson Lab, U.S. Department of Energy. MeSH.
Europium phosphors are used in televisions, fluorescent lighting, and some LEDs. Europium's compound, Europium Oxide, is often used as a phosphor activator. europium synonyms, europium pronunciation, europium translation, English dictionary definition of europium. Europium's other two roles are also involved with phosphors. It glows red under UV light, and forgeries can be detected by the lack of this red glow. It is also used in fluorescent lights in addition to other Europium doped glasses. With the development of ion-exchange techniques and special processes, the cost of the metal has been greatly reduced in recent … Europium is used as a doping agent in glass, laser and optoelectronic devices. Europium is a rare earth element that can be found in varying quantities in most rare-earth containing minerals. 1 Structures Expand this section. Europium is used in the printing of euro banknotes. During the process, a silvery-white metallic substance containing europium is deposited on the walls of the container. It is also used in scintillators for X-ray tomography and as a source of blue color in light-emitting diode s (LEDs). Whereas trivalent europium gives red phosphors, the luminescence of divalent europium depends on the host lattice, but tends to be on the blue side. Europium oxide (Eu 2 O 3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. Contents. Europium is the least dense, the softest, and the most volatile member of the lanthanide series. Its oxides Eu 2 O 3 is widely used as red phosphor in television sets and fluorescent lamps. Europium (Eu), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
It is also used in the preparation of fluorescent glass. 5 Chemical Vendors.
