Exempel på hur man kan använda ERBIUM i en mening

• A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.
• Ytterby is most famous for being the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, and five more elements were also first discovered there.
• The rare earth element holmium is identified in erbium by Marc Delafontaine and Jacques-Louis Soret in Geneva and by Per Teodor Cleve in Sweden.
• Another unsuccessful attempt to synthesize unbibium was carried out in 1978 at the GSI Helmholtz Center, where a natural erbium target was bombarded with xenon-136 ions:.
• In 1864, Marc Delafontaine used optical spectroscopy to conclusively prove that yttrium, terbium, and erbium were separate elements.
• The rare-earth elements dysprosium, erbium, terbium and ytterbium, as well as metal elements such as thorium and uranium (all replacing yttrium) are the expressive secondary components of xenotime.
• Rare earth elements such as neodymium and erbium can be doped into YAG as active laser ions, yielding Nd:YAG and Er:YAG lasers, respectively.
• The scientists used a pyroelectric crystal heated from , combined with a tungsten needle to produce an electric field of about 25 gigavolts per meter to ionize and accelerate deuterium nuclei into an erbium deuteride target.
• Other neutron absorbers used in nuclear reactors are xenon, cadmium, hafnium, gadolinium, cobalt, samarium, titanium, dysprosium, erbium, europium, molybdenum and ytterbium.
• The village of Ytterby, famous among chemists for naming no fewer than four chemical elements (erbium, terbium, ytterbium and yttrium), is situated on Resarö in the Stockholm Archipelago.
• In QUADRISO particles a burnable neutron poison (europium oxide or erbium oxide or carbide) layer surrounds the fuel kernel of ordinary TRISO particles to better manage the excess of reactivity.
• The oxide, also called holmia, occurs as a component of the related erbium oxide mineral called erbia.
• Forbidden transitions in rare earth atoms such as erbium and neodymium make them useful as dopants for solid-state lasing media.
• A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium.
• Each ultrasonically formed erbium oxide exhibits photoluminescence in the visible region of the electromagnetic spectrum under excitation of wavelength 379 nm in water.
• This is a common construction also seen in Itterby, one of the parishes which formed Cleethorpes, and also Ytterby in Sweden, which is relatively frequent in Scandinavia and from which derive the names of the Chemical elements Yttrium, Ytterbium, Terbium and Erbium.
• Samples of YLF and YAG crystals doped with erbium, thulium, and holmium are being studied with selective laser excitation in the region of 780 nm, the erbium bands.
• Modeling of erbium: YAG laser-mediated explosive photovaporization: implications for vitreoretinal surgery.
• The procedure of doping tiny amounts of the metals chromium (Cr), neodymium (Nd), erbium (Er), thulium (Tm), ytterbium (Yb), and a few others, into transparent crystals, ceramics, or glasses is used to produce the active medium for solid-state lasers.
• If this ion is erbium, then a characteristic green and red emission is observed, while when the upconverter ion is thulium, the emission includes near-ultraviolet, blue and red light.
