An interesting example is the controlled decomposition of polytetrafluoroethene for the generation of tetrafluoroethene which is used as a hydroxide scavenger in the processing and growth of metal fluoride single crystals. 

An important practical example of the second case is the lanthanum fluoride single-crystal electrode, permeable to fluoride ion but not to cations. Construct a cell...

In the course of a study of the luminescence properties of uranium-doped sodium fluoride single crystals, the complicated uranate luminescence spectra have been unraveled, using chemical variation of the crystal compositions and by applying site selective laser excitation techniques Using the results from both luminescence and electrical conductivity experiments a model was deduced for the configurations of the uranium centres ). 

In Sect. 4.2 the luminescence and electrical conductivity of uranium-activated sodium-fluoride single crystals will be discussed, whereas in Sect. 4.3 the laser excited luminescence experiments will be dealt with.

INTRODUCTION This data sheet summarizes properties of sodium fluoride single crystals. 

Solid-state sensors for chloride, iodide, and fluoride are based on the solubility product of silver chloride or silver iodide particles in silicone rubber and a doped lanthanum fluoride single crystal, respectively. The fluoride-selective electrode was applied for the analysis of urine and bone tissue of people exposed to industrial sources as well as for control of therapeutic fluoride application for osteoporosis, whereas the chloride-selective sensor was applied to the analysis of sweat for the diagnosis of cystic fibrosis. In solid-state contact electrodes the solvent polymeric membrane is directly contacted to the solid field transducing element, although the reference electrode is separated from the ion-selective sensing pad. 

An attempt has been made to measure oxygen concentration by using a fluorine conducting electrolyte (Yamazoe et al. 1987, Miura et al. 1987, 1989, Kuwata et al. 1984a,b). Yamazoe et al. (1987) proposed an oxygen gas sensor with a lanthanum fluoride single crystal electrolyte. Lanthanum fluoride is feasible in an aqueous environment and has been used to detect dissolved oxygen in water.
