Erbium is a chemical element in the lanthanide series, with the symbol Er and atomic number 68. natural
erbium is always found in
Kaynak: Erbium Naturally occurring
erbium (Er) is composed of 6 stable isotope s, 162 Er, 164 Er, 166 Er, 167 Er, 168 Er, and 170 Er with 166 Er being the
Kaynak: Isotopes of erbiumErbium(III) oxide, is synthesized from the transition metal
erbium. It was partially isolated by Carl Gustaf Mosander in 1843, and first
Kaynak: Erbium(III) oxide Erbium(III) chloride, the
erbium (III) salt of hydrochloric acid , is a violet solid used for the preparation of
erbium metal.
Kaynak: Erbium(III) chloride The most common example is the
Erbium Doped Fiber Amplifier (EDFA), where the core of a silica fiber is doped with trivalent
erbium ions
Kaynak: Optical amplifieranother independent component, which he called "ytterbia", for Ytterby , the village in Sweden near where he found the new component of
erbium .
Kaynak: Ytterbium(confusingly, this was called 'erbia' at the time) and rose-colored
erbium oxide (called 'terbia' at the time A fourth oxide, ytterbium
Kaynak: YttriumUnder trichromatic light, it is a fiery orange red, almost indistinguishable from the appearance of
erbium oxide under the same lighting
Kaynak: HolmiumThe earth giving pink salts he called terbium; the one which yielded yellow peroxide he called
erbium. lanthanum, didymium,
erbium and terbium.
Kaynak: Rare earth elementThe primary decay product s before 169 Tm are element 68 (
erbium ) isotopes, and the primary products after are element 70 (ytterbium )
Kaynak: ThuliumThe rare earths dysprosium ,
erbium , terbium , and ytterbium , and metal elements like thorium and uranium (all replacing yttrium) are
Kaynak: XenotimeHe discovered the elements lanthanum ,
erbium and terbium . Mosander went to school in Kalmar until he moved to Stockholm with his mother
Kaynak: Carl Gustaf Mosander(due to what is now known as
erbium), and "erbia" was the fraction that was essentially colorless in solution, but gave a brown-tinged oxide.
Kaynak: Terbiummedium is an optical fiber doped with rare-earth element s such as
erbium , ytterbium , neodymium , dysprosium , praseodymium , and thulium .
Kaynak: Fiber laserYtterbium , holmium , thulium , and
erbium are other common "dopants" in solid-state lasers. Ytterbium is used in crystals such as Yb:YAG
Kaynak: LaserThe oxide, also called holmia, occurs as a component of the related
erbium oxide mineral called erbia . Typically the oxides of the
