Europium is a chemical element; it has symbol Eu and atomic number 63. It is a silvery-white metal of the lanthanide series that reacts readily with air to form a dark oxide coating. Europium is the most chemically reactive, least dense, and softest of the lanthanides. It is soft enough to be cut with a knife.
For example, europium(III) oxide can be used in picture tube televisions [67] and europium-doped yttrium oxysulfide (Y 2 O 2 S:Eu 3+) can be used as phosphors. [68] In addition, europium compounds can also be used in the manufacture of anti-counterfeiting materials.
Europium(III) oxide (Eu 2 O 3), is a chemical compound of europium and oxygen. It is widely used as a red or blue phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. It is also an agent for the manufacture of fluorescent glass. Europium fluorescence is used in the anti-counterfeiting phosphors in ...
Europium(II) sulfide is the inorganic compound with the chemical formula EuS. It is a black, air-stable powder . Europium possesses an oxidation state of +II in europium sulfide, whereas the lanthanides exhibit a typical oxidation state of +III. [ 1 ]
Handbook of Chemistry and Physics (53rd ed.). Cleveland, Ohio: Chemical Rubber Co. ... Europium(III) chloride can be used as a starting point for the preparation of ...
Strontium aluminate is an aluminate compound with the chemical formula SrAl 2 O 4 (sometimes written as SrO·Al 2 O 3). It is a pale yellow, monoclinic crystalline powder that is odourless and non-flammable. When activated with a suitable dopant (e.g. europium, written as Eu:SrAl 2 O 4), it acts as a photoluminescent phosphor with long ...
EuFOD is the chemical compound with the formula Eu(OCC(CH 3) 3 CHCOC 3 F 7) 3, also called Eu(fod) 3. This coordination compound is used primarily as a shift reagent in NMR spectroscopy. It is the premier member of the lanthanide shift reagents and was popular in the 1970s and 1980s.
Europium oxide is a compound from the two elements europium and oxygen. Europium oxide may refer to: Europium(II) oxide (europium monoxide, EuO) a magnetic semiconductor. Europium(III) oxide (europium sesquioxide, Eu 2 O 3), the most common oxide.
