Résumé

Single-phase BaF$_2$ : Ce solid solutions containing 30 – 40 mol. % cerium with the simultaneous entry of potassium into the crystal lattice in an amount of 0.7 – 0.8 mol. % were prepared by coprecipitation from aqueous nitrate solutions with potassium fluoride as the fluoridating agent. The cerium X-ray luminescence intensity increases in response to increasing cerium concentration contrary to the concentration quenching effect.

Keywords: barium fluoride, cerium
Mots-clés : X-ray luminescence.
