Erbium-doped glasses or crystals can be used as optical amplification media, where Er3+ ions are optically pumped at around 980 or 1480 nm and then radiate light at 1530 nm in stimulated emission. Analytical, Diagnostic and Therapeutic Techniques and Equipment 13. K.W. This color behavior is similar to what Mosander and the other early workers in the lanthanides would have seen in their extracts from the gadolinite minerals of Ytterby.

[8], Erbium (for Ytterby, a village in Sweden) was discovered by Carl Gustaf Mosander in 1843. These dopants help prevent clustering of Er ions and transfer the energy more efficiently between excitation light (also known as optical pump) and the signal. The highest concentration of erbium in humans is in the bones, but there is also erbium in the human kidneys and liver. Erbium Overview Er Group Number lanthanides Atomic Number 68 Learn more about the atomic number. What's in a name? Benjamin Brenny (2017, TNO) This element also has 13 meta states, with the most stable being 167mEr with a half-life of 2.269 s.[8], The isotopes of erbium range in atomic weight from 142.9663 u (143Er) to 176.9541 u (177Er). Erbium Group is an entity registered at California with company number C3971246. Their current partial address is Dublin 2, and the company status is Normal. Number of protons in Erbium is 68. Name Origin Named after the Swedish town, Ytterby. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth. 68 Er Erbium 167.259. Erbium's principal uses involve its pink-colored Er3+ ions, which have optical fluorescent properties particularly useful in certain laser applications. Regular visitors. [4], Erbium is ferromagnetic below 19 K, antiferromagnetic between 19 and 80 K and paramagnetic above 80 K.[5], Erbium can form propeller-shaped atomic clusters Er3N, where the distance between the erbium atoms is 0.35 nm. Its sesquioxide is called erbia. A spectroscopist mistakenly switched the names of the two elements during spectroscopy. [citation needed], Erbium-doped optical silica-glass fibers are the active element in erbium-doped fiber amplifiers (EDFAs), which are widely used in optical communications. Naturally, occurring Erbium is found in chemical combination with other naturally occurring elements. Erbium (chemical symbol: Er) is a chemical element belonging to the group of rare earth metals. Erbium's everyday uses are varied. Technical data for Erbium Click any property name to see plots of that property for all the elements. Atomic Mass 167,26 Learn more about the atomic mass. Erbium: Symbol: Er: Atomic Number: 68: Atomic Mass: 167.259 atomic mass units: Number of Protons: 68: Number of Neutrons: 99: Number of Electrons: 68: Melting Point: 1522.0° C: Boiling Point: 2510.0° C Density: 8.795 grams per cubic centimeter: Normal Phase: Solid: Family: Rare Earth Metals: Period: 6: Cost: $650 per kilogram Atomic Number of Erbium is 68.. Chemical symbol for Erbium is Er. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife.The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden, from which it got its name. Element Erbium (Er), Group 19, Atomic Number 68, f-block, Mass 167.259. Named after Ytterby, a village in Sweden. In the high-yttrium versions of these ore concentrates, yttrium is about two-thirds of the total by weight, and erbia is about 4–5%. Current status of the company is Active. Not found any post match with your request, STEP 2: Click the link on your social network, Can not copy the codes / texts, please press [CTRL]+[C] (or CMD+C with Mac) to copy, How a small number of atoms can be joined and form completely different substances. It is commonly used as a photographic filter,[20] and because of its resilience it is useful as a metallurgical additive. It is a soft, malleable, lustrous & silvery metal. Its atomic weight is 167.259. Period Number: 6. Atomic Number: 68. Erbium Group’s experienced and professional website maintenance and support team is capable of maintaining your website without compromising on the quality. Erbium is a chemical element with the symbol Er and atomic number 68. When it is artificially isolated its appearance is a silvery-white solid metal. The oxides are dissolved in nitric acid that excludes one of the main components, cerium, whose oxide is insoluble in HNO3. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. Registered agent is Laura Semerjian, 34319 Lamborn St Temecula CA 92592. Erbium's properties are to a degree dictated by the kind and amount of impurities present. [21] The same fibers can be used to create fiber lasers. Erbium is a chemical element with the symbol Er and atomic number 68. Texas at Austin) Harry Atwater (Caltech) Javier Garcia de Abajo (ICFO, Barcelona) Marc Verschuuren (Philips Research) Academic research family tree for former group members in academia Former Ph.D. students. The primary decay mode before the most abundant stable isotope, 166Er, is electron capture, and the primary mode after is beta decay. Other erbium compounds include: erbium fluoride (ErF 3, erbium chloride (ErCl 3 and erbium iodide (ErI 3). After 1860, terbia was renamed erbia and after 1877 what had been known as erbia was renamed terbia. dermatology, dentistry) utilize erbium ion's 2940 nm emission (see Er:YAG laser), which is highly absorbed in water (absorption coefficient about 12000/cm).
