Ytterbium doped Potassium-Gadolinium Tungstate is a crystalline solid used in photo optic applications. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Ytterbium has 2 valency state, +2 +3. The electronic configuration is [Xe]4f146s2. In its metallic form Ytterbium's CAS number is 7440-64-4 and its standard state @ 20 ºC is a solid. The Ytterbium atom has a radius of 194 pm and it's Van der Waals radius is unknown. On the periodic table, Ytterbium is a Block F, Group 3, Period 6 element.

Potassium is a Block S, Group 1, Period 4 element. The electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes in water with the evolution of hydrogen. It catches fire spontaneously in water.

Gadolinium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f75d16s2. In its elemental form gadolinium's CAS number is 7440-54-2. The gadolinium atom has a radius of 178.7.pm and it's Van der Waals radius is unknown. Gadolinium is utilized for both its high magnetic moment (7.94µB) and in phosphors and scintillator material. When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. Gadolinium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.

Tungsten is a Block D, Group 6, Period 6 element. The electronic configuration is [Xe] 4f14 5d4 6s2. In its elemental form tungsten's CAS number is 7440-33-7. The tungsten atom has a radius of 137.pm and it's Van der Waals radius is 200.pm. Tungsten has the highest melting point of all the metallic elements and because of this has its first significant commercial application as the filament in incandescent light bulbs and fluorescent light bulbs. Tungsten is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Later it was used in the first television tubes.
