The scintillation properties of Ce 3+ doped ternary cesium rare‐earth halides are reported. We investigated Cs 3 Lu 2 I 9 :Ce 3+ , Cs 3 Gd 2 I 9 :Ce 3+ , Cs 3 LaBr 6 :Ce 3+ and Cs 3 LuI 6 :Ce 3+ . Cs 3 Lu 2 I 9 :Ce 3+ and Cs 3 LaBr 6 :Ce 3+ exhibit the highest light yields under γ‐ray excitation of 22800 ± 2300 and 10400 ± 1000 photons per MeV of absorbed γ‐ray energy, respectively. Optical spectroscopy and scintillation decay time curves of these compounds are presented. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
