Conference paper


Thermoluminescent spectra of alkaline earth fluoride crystals doped with scandium and lanthanum ions have heen compared with those of yttrium doped crystals. The spectra are interpreted in terms of associated donor-acceptor pairs involving interstitial sites or vacancies in the fluoride sublattice. The pair spectra due to transitions between the thermally-stimulated excited state and the ground state are dependent on pair internuclear distance. On the basis of this model conclusions on coordination number and symmetry of the dopant sites are drawn.
