Abstract

IN a letter in NATURE of January 19, 19351, I stated that the blue fluorescence shown by fluorites is due to bivalent europium produced through reduction of traces of trivalent europium by radium nays. In the same way a yellow-green band shown by some fluorites at low temperatures can be ascribed to bivalent ytterbium. Later2, it was shown that a red fluorescence band that had puzzled us a good deal is due to bivalent samarium.
