Ytterbium has three allotropes which are called alpha, beta and gamma and whose transformation points are at −13 °C and 795 °C. Allotropy (Gr allos, other and tropos, manner is a behavior exhibited by certain Chemical elements these elements can exist in two or more different The Celsius Temperature scale was previously known as the centigrade scale. The beta form exists at room temperature and has a face-centered crystal structure while the high-temperature gamma form has a body-centered crystal structure. In Mineralogy and Crystallography, a crystal structure is a unique arrangement of Atoms in a Crystal.

Ytterbium is one of the lanthanides that is able to become divalent. Like the other potentially divalent lanthanides, samarium and europium, it is capable of being extracted into mercury by the use of sodium amalgam, which made it one of the easier lanthanides to purify using classical techniques. However, this divalency was not discovered until the 20th century.
Usually, very small amount of Yb is used; either small sample of radioactive isotope as source of X-rays, or small concentration dopant. X-radiation (composed of X-rays) is a form of Electromagnetic radiation.
The 169Yb isotope has been used as a radiation source substitute for a portable X-ray machine when electricity was not available. Isotopes (Greek isos = "equal" tópos = "site place" are any of the different types of atoms ( Nuclides Radiation, as in Physics, is Energy in the form of waves or moving Subatomic particles emitted by an atom or other body as it changes from a higher energy X-radiation (composed of X-rays) is a form of Electromagnetic radiation. Like X-rays, gamma rays pass through soft tissues of the body, but are blocked by bones and other dense materials. Gamma rays (denoted as &gamma) are a form of Electromagnetic radiation or light emission of frequencies produced by sub-atomic particle interactions Thus, small 169Yb samples (which emit gamma rays) act like tiny X-ray machines useful for radiography of small objects. For medical radiography see Radiology Radiography is the use of X-rays to view unseen or hard-to-image objects

Yb is used as dopant in optics materials, usually in the form of ions in active laser media. An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge The active laser medium or gain medium is the source of optical Gain within a Laser. Several powerful double-clad fiber lasers and disk lasers use Yb3+ ions as dopant at concentration of several atomic percent. In Fiber optics, a double-clad fiber (or doubly clad fiber or DCF is an Optical fiber that has a relatively small-diameter core and two layers A disk laser or active mirror (Fig1 is a type of Solid-state laser characterized by a heat sink and laser output that are realized on opposite sides of A dopant, also called doping agent and dope, is an impurity element added to a crystal or semiconductor lattice in low concentrations in order to alter the optical/electrical Atomic percent or at% is a measure of Concentration of Dopant, used in Chemistry, physics of Solid state lasers and Spectroscopy Glasses (optical fibers), crystals and ceramics with Yb3+ are used.
Ytterbium is often used as a doping material (as Yb3+) for high power and wavelength-tunable solid state lasers. In Semiconductor production doping is the process of intentionally introducing impurities into an extremely pure (also referred to as intrinsic) semiconductor to A solid-state laser is a Laser that uses a gain medium that is a Solid, rather than a Liquid such as in Dye lasers or a Gas Yb lasers commonly radiate in the 1. 06–1. 12µm band being optically pumped at wavelength 900nm–1µm, dependently on the host and application. Small quantum defect makes Yb prospective dopant for efficient lasers and power scaling. Power scaling of a Laser is increasing its output power without changing the geometry shape or principle of operation
The kinetic of excitations in Yb-doped materials is simple and can be described within concept of effective cross-sections; for the most of Yb-doped laser materials (as for many other optically-pumped gain media), the McCumber relation holds [1][2][3], although the application to the Yb-doped composite materials was under discussion [4][5]. The McCumber relation (or McCumber theory refers to the effective cross-sections of absorption and emission of light in the physics of Solid-state lasers. Composite materials (or composites for short are engineered Materials made from two or more constituent materials with significantly different physical or chemical
Usually, low concentrations of Yb are used. At high concentration of excitations, the Yb-doped materials show photodarkening [6] (glass fibers) or ever switch to the broadband emission [7] (crystals and ceramics) instead of the efficient laser action. Photodarkening is Optical effect observed in interaction of laser radiation with amorphous media (glasses in Optical fibers. This effect may be related with not only overheating, but also conditions of the charge compensation at high concentration of Yb ions [8].
Ytterbium has a single absorption band at 985 nanometers, which is used to convert infrared energy into electricity in solar cells. An absorption band is a range of Wavelengths (or equivalently frequencies) in the Electromagnetic spectrum which are able to excite a particular The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International Infrared ( IR) radiation is Electromagnetic radiation whose Wavelength is longer than that of Visible light, but shorter than that of A solar cell or photovoltaic cell is a device that converts Solar energy into Electricity by the photovoltaic effect.
Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in 1878. Jean Charles Galissard de Marignac ( April 24, 1817 &ndash April 15, 1894) was a Swiss chemist whose work with Year 1878 ( MDCCCLXXVIII) was a Common year starting on Tuesday (link will display the full calendar of the Gregorian calendar (or a Common Marignac found a new component in the earth then known as erbia and named it ytterbia (after Ytterby, the Swedish town where he found the new erbia component). Erbium(III oxide, a pink solid is a compound of Erbium sometimes used as a colouring for Glasses and a dopant for optical fibres and optical amplifiers Ytterby is a village on the Swedish island of Resarö, in Vaxholm Municipality in the Stockholm archipelago. He suspected that ytterbia was a compound of a new element he called ytterbium.
In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components, neoytterbia and lutecia.

Rare earth elements and rare earth metals are according to IUPAC, the collection of seventeen Chemical elements in the Periodic table, namely A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific It is most often recovered commercially from monazite sand (0. In Geology, the Mineral monazite is a reddish-brown Phosphate -containing rare earth metals and an important source of Thorium 03% ytterbium). The element is also found in euxenite and xenotime. Euxenite or euxenite-(Y (a correct mineralogical name is a brownish black Mineral with a metallic luster. Xenotime (from the Greek words xenos, "foreign" and time, "honour" is a Rare Earth phosphate mineral whose major Ytterbium is normally difficult to separate from other rare earths but ion-exchange and solvent extraction techniques developed in the late 20th century have simplified separation. Ion exchange is an exchange of Ions between two Electrolytes or between an electrolyte Solution and a complex. Liquid-liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds based on their relative solubilities in two The twentieth century of the Common Era began on Known compounds of ytterbium are rare—they haven't been well characterized yet. A chemical compound is a substance consisting of two or more different elements chemically bonded together in a fixed proportion by Mass.
Naturally occurring ytterbium is composed of 7 stable isotopes, Yb-168, Yb-170, Yb-171, Yb-172, Yb-173, Yb-174, and Yb-176, with Yb-174 being the most abundant (31.

The unified atomic mass unit ( u) or Dalton ( Da) or sometimes universal mass unit, is an unit of Mass used to express 9562 u (Yb-181). The primary decay mode before the most abundant stable isotope, Yb-174 is electron capture, and the primary mode after is beta emission.

Although ytterbium is fairly stable, it nevertheless should be stored in closed containers to protect it from air and moisture. All compounds of ytterbium should be treated as highly toxic although initial studies appear to indicate that the danger is limited. Toxicity is the degree to which a substance is able to damage an exposed organism Ytterbium compounds are, however, known to cause skin and eye irritation and may be teratogenic. The skin is the outer covering of living tissue of an animal (or plant Eyes are organs that detect Light, and send signals along the Optic nerve to the visual areas of the brain Teratology stems from the Greek ( Genitive) meaning monster, or marvel and, meaning word, speech. Metallic ytterbium dust poses a fire and explosion hazard. Fire is the heat and light energy released during a Chemical reaction, in particular a combustion reaction. An explosion is a sudden increase in Volume and release of Energy in an extreme manner usually with the generation of high Temperatures and the release
