Erbium

Erbium is a rare earth element which is associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. It is also used in nuclear technology in neutron-absorbing control rods. When added to vanadium as an alloy, erbium lowers hardness and improves work ability. Erbium oxide has a pink color, and is sometimes used as a colorant for glass, cubic zirconia and porcelain. The glass is then often used in sunglasses and cheap jewelry. Erbium-doped optical silica-glass fibers are the active element in erbium-doped fiber amplifiers, which are widely used in optical communications. A large variety of medical applications utilize erbium ion's 2940 nm emission, which is highly absorbed in water. Such shallow tissue deposition of laser energy is necessary for laser surgery, and the efficient production of steam for laser enamel ablation in dentistry.

Europium

Europium is a chemical element, which was named after the continent of Europe. It is a moderately hard silvery metal which readily oxidizes in air and water. It has no significant biological role and is relatively non-toxic compared to other heavy metals. It is a dopant in some types of glass in lasers and other optoelectronic devices. It is also used in the manufacture of fluorescent glass. Europium oxide is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. Europium fluorescence is used to interrogate biomolecular interactions in drug-discovery screens. It is also used in the anti-counterfeiting phosphors in Euro banknotes.

Fluorine

Fluorine is the most electronegative and reactive of all elements. Natural fluorine is monoisotopic, consisting of fluorine-19. It has found uses in studies of protein structures and conformational changes. Elemental fluorine is occasionally used as a fluorinating agent in industrial processes. The largest use for elemental fluorine is preparing uranium hexafluoride, used in the production of nuclear fuels. Other than those, elemental fluorine is used for the production of tetrafluoromethane, plasma etching in semiconductor manufacturing, flat panel display production, and microelectromechanical systems fabrication. Inorganic fluorides and organofluorine compounds, a fraction of which are prepared from elemental fluorine, find use in a variety of materials and chemicals, including important pharmaceuticals, agrochemicals, lubricants, and textiles. Hydrofluoric acid and certain fluoride-containing salts are useful etchants for glass. In the electrolysis of the metal and its purification, it acts to lower the melting point of aluminium oxide and acts like a powerful flux for glass. Perfluorooctanoic acid and tetrafluoroethylene are directly used in water resistant coatings and in the production of low friction plastics such as Teflon, or PTFE. Other fluorine-based compounds are used in the production of haloalkanes such as chlorofluorocarbons, which are used extensively in air conditioning and in refrigeration. They have been banned for these applications because they contribute to ozone destruction.
