Single-phase BaF2: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.

Однофазные твердые растворы BaF2:Ce, содержащие 30-40 мол.% церия и 0.7-0.8 мол.% калия были получены методом соосаждения из водных нитратных растворов при использовании фторида калия в качестве фторирующего агента. Интенсивность рентгенолюминесценции церия увеличивается при увеличении содержания церия вопреки эффекту концентрационного тушения.
