Abstract

The authors employed various physical and chemical methods for the purification of NaF. The efficiency of these methods was controlled by absorption measurements and chemical analysis. From purified material a single crystal was grown in every case, the absorption of which was measured by a vacuum ultraviolet spectrophotometer in the far UV wavelength range. The absorption at 142 nm was found to be indicative of the presence of several transition and heavy metal ions. The effect of doping with several alkaline and alkaline earth ions and furthermore with Cl and OH ions on these spectra is discussed. It is shown that certain chemical methods used for purification introduce Cl ions into the material which are detectable by UV‐spectrophotometry.
