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.
Global Medical Device Nomenclature (GMDN) is a system of internationally agreed generic descriptors used to identify all medical device products. This nomenclature is a naming system for products which include those used for the diagnosis, prevention, monitoring, treatment or alleviation of disease or injury in humans.
It is a dopant in some types of glass in lasers and other optoelectronic devices. Europium oxide (Eu 2 O 3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. [51] [52] Color TV screens contain between 0.5 and 1 g of europium oxide. [53]

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 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) 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 ]
Anhydrous EuCl 3 is often prepared by the "ammonium chloride route," starting from either Eu 2 O 3 [1] [2] or hydrated europium chloride (EuCl 3 ·6H 2 O) by heating carefully to 230 °C. [3] These methods produce (NH 4 ) 2 [EuCl 5 ]:
