Abstract

Electron spin resonance has been used to follow the changes of site symmetry that occur in rare‐earth‐doped SrF₂. The main conclusions that may be drawn are that the variation of site from tetragonal to trigonal as one goes through the rare‐earth series Ce³⁺ to Er³⁺ can be explained by a calculation of the relative energies of interstitial fluorine ions and that the concentration dependence of the trigonal and cubic sites of Er³⁺‐doped SrF₂ can be explained by the sweeping action of dislocations for both the charge compensating and erbium ions.
