Luminescence of cerium in BaThF 6 and PbThF 6

Luminescence properties of cerium in the dense tysonite-type BaThF 6 and PbThF 6 hosts have been investigated. In the barium phase the emission shows high quantum efficiency at 300 K. In PbThF 6 strong thermal quenching above 20 K is ascribed to photoionization of Ce 3+ ions. The high density and fa...

Summary:Luminescence properties of cerium in the dense tysonite-type BaThF 6 and PbThF 6 hosts have been investigated. In the barium phase the emission shows high quantum efficiency at 300 K. In PbThF 6 strong thermal quenching above 20 K is ascribed to photoionization of Ce 3+ ions. The high density and fast decay of BaThF 6 : Ce makes this material attractive for particle detection.
