Enhancement of Europium Emission Band of Europium Tetracycline Complex in the Presence of Cholesterol

Journal of Fluorescence, 2007
We report here the observation, for the first time, of the enhancement of Europium-Tetracycline complex emission in cholesterol solutions. This enhancement was initially observed with the addition of the enzyme cholesterol oxidase, which produces H(2)O(2), the agent driver of the Europium tetracycline complex, to the solution.

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.

Mössbauer Measurements in Europium-Calcium and Europium-Strontium Alloys

Journal of Applied Physics, 1970
Mössbauer effect measurements have been performed for EuxCa1−x and EuxCa1−x (0≤x≤1) alloys using the 22-keV γ-line in 151Eu. The hyperfine (hf) fields extrapolated to zero europium content are −110 kOe for the EuCa system and −140 kOe for the CuSr system as compared to −150 kOe for the EuBa and EuYb system.

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.
