Mössbauer studies of 151Eu in europium oxalate, europium bissalen ammonium and europium benzoate

Hyperfine Interactions, 2006
Although a number of europium water insoluble chelates have been prepared for several decades, the covalent nature of these compounds has never been established in any quantitative fashion. Shifts in the I.R. bands and conductivity measurements of these salts were hitherto used to qualitatively compare their molecular nature. In this communique we have

Labeling Antibodies Using Europium

Cold Spring Harbor Protocols, 2020
There are many uses for antibodies labeled with metal ions. Most of these methods involve first attaching a metal chelator to the antibody molecule. This is achieved using standard cross-linking chemistry and then adding the desired metal at appropriate concentration and pH. The method described here outlines a basic procedure for creating a lanthanide

Fluorescent Europium Chelate Stain

Journal of Bacteriology, 1969
The europium chelate of 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (thenoyl-trifluoroacetone; TTA) is firmly bound to microorganisms. It fluoresces brightly at 613 nm with activation at 340 nm. Cells may be stained with 10 −3 m chelate in 50% ethyl alcohol, followed by washing with 50% ethyl alcohol ...

Europium-151 Mössbauer effect study of europium orthovanadite

Hyperfine Interactions, 1992
151Eu Mossbauer spectroscopy on Eu VO3 in the temperature range of 9-293 K indicated that there is a large increase ofeV zzQg when temperature goes from 293K down to 9K.

Gadolinium Doped Europium Sulfide

Journal of the American Chemical Society, 2010
We have prepared gadolinium doped europium sulfides, Eu(1-x)Gd(x)S for a doping range of 0 ≤ x ≤ 0.1 by thermal decomposition of the precursors Eu(S(2)CNEt(2))(3)Phen/Gd(S(2)CNEt(2))(3)Phen with respective ratios. Electron doping provides indirect evidence for the magnetic coupling through carrier electrons in magnetic semiconductors.

Europium – praktisch

Nachrichten aus der Chemie
AbstractSeltene Erden nehmen im Studium häufig eine Nischenrolle ein. Dabei gab es in den USA bereits im Jahr 1967 wissenschaftliche Abhandlungen für Schulen zu diesem Thema. Und Lanthanoide können mehr als kontrahieren – das zeigen drei Beispiele für Praktikum und Vorlesung.

Zeeman-Effekt des dreiwertigen Europiums im Europium-Bromat

Zeitschrift f�r Physik, 1959
Der Zeeman-Effekt des sichtbaren Absorptionsspektrums wird bei 201 °K mit hoher Auflosung untersucht. Die beobachteten Linienverschiebungen lassen sich durch eine Storungsrechnung erster Naherung mit dem bei dieser Temperatur pseudomonoklinen Kristallfeld und dem auseren Magnetfeld als Storung des Eu-Ions vollstandig beschreiben.
