europium
n 1: a bivalent and trivalent metallic element of the rare earth
group [synonym: {europium}, {Eu}, {atomic number 63}]

Europium \Eu*ro"pi*um\, n. [NL.; Europe -ium, as in
aluminium.] (Chem.)
A metallic element of the rare-earth group (Lanthanide
series), discovered spectroscopically by Demarcay in 1896.
Symbol, Eu; atomic number 63; at. wt., 151.965 (C=12.011);
valence = 2 or 3.

  • Europium - an overview | ScienceDirect Topics
    Europium (III) refers to the trivalent form of europium, a lanthanide element that is characterized by intense red photoluminescence and serves as a spectroscopic probe for determining the symmetry of lanthanide sites AI generated definition based on: Coordination Chemistry Reviews, 2015
  • Europium anomalies in zircon: A signal of crustal depth?
    Europium anomalies in melt in anatectic systems are controlled by the bulk rock composition, the phase assemblage (including plagioclase, alkali feldspar, and the other minerals), and oxygen fugacity There is an interplay between the changing oxidation state of Eu and the role of the minerals that preferentially partition trivalent Eu
  • Europium-Doped CsPbI2Br for Stable and Highly Efficient Inorganic . . .
    Here, we show that europium doping of CsPbI2Br stabilizes the α phase of this inorganic perovskite at room temperature We rationalize it by using solid-state nuclear magnetic resonance and high-angle annular dark-field scanning transmission electron microscopy, which show that europium is incorporated into the perovskite lattice
  • Interpretation of europium(III) spectra - ScienceDirect
