Terbium Acetylacetonate is a Terbium source that is soluble in organic solvents. The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring.Because of this property, Terbium Acetylacetonate is commonly used in various catalysts and catalytic reagents for organic synthesis. It is generally immediately available in most volumes. Ultra high purity and high purity forms may be considered. Terbium Acetylacetonate is one of numerous organo-metallic compounds sold by American Elements under the tradename AE Organo-Metallics™ for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Similar results can sometimes also be achieved with Nanoparticles (also see Nanotechnology and Quantum Dots) and by thin film deposition. Note American Elements additionally supplies many materials as solutions. The numerous commercial applications for Terbium includephosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Terbium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f96s2. In its elemental form terbium's CAS number is 7440-27-9. The terbium atom has a radius of 176.3.pm and it's Van der Waals radius is unknown. Terbium is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety. Terbium 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.
