Abstract
The fluorescence and absorption spectra of various uranium-activated sodium fluoride phosphors have been studied at liquid-nitrogen and liquid-helium temperatures. These results are interpreted in terms of a model in which the uranium ion is surrounded octahedrally by six oxygen ions. Experiments with18O have provided support for this atomic configuration, several lines in the fluorescence spectrum having an isotope shift. These isotope shifts are in agreement with the predictions of a general theory of the vibrational fine structure in luminescence spectra.Keywords
