An application that has almost fallen out of use with the introduction of affordable superconducting magnets is the use of europium complexes, such as Eu(fod) 3, as shift reagents in NMR spectroscopy. Chiral shift reagents, such as Eu(hfc) 3, are still used to determine enantiomeric purity. [60]
Europium compounds fluoresce under UV light at 395 nm and 365 nm. [1] Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl 3, Eu(NO 3) 3 and Eu(CH 3 COO) 3. Compounds with europium in the +2 oxidation state are also known.
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 ...
Treating Eu 2 O 3 with aqueous HCl produces hydrated europium chloride (EuCl 3 ·6H 2 O). This salt cannot be rendered anhydrous by heating. Instead one obtains an oxychloride. ...
Europium(III) hydroxide is an inorganic compound with a chemical formula Eu(OH) 3. Chemical properties. Europium(III) hydroxide can be prepared by reacting metallic ...
Europium(III) nitrate is an inorganic compound with the formula Eu(NO 3) 3 ·x(H 2 O). The hexahydrate is a common salt. The hexahydrate is a common salt. It forms colorless hygroscopic crystals.
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.
Europium(II) sulfate is the inorganic compound with the formula EuSO 4. Two polymorphs are known, α and the more stable β. Both are colorless. The β polymorph is isostructural with barium sulfate, hence it is insoluble in water. The salt is generated by addition of soluble europium(II) salts to dilute sulfuric acid. [1]
