The Light Emitted by Europium Compounds

Abstract

SOME time ago, my co-workers and I 1 found that the well-known blue fluorescence band of some fluorites is due to traces of bivalent europium. In later papers2, I showed that europium can easily be reduced to the bivalent form by heating in various basic materials.
