Abstract

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)

LaI 3 :Ce 3+ has the smallest band gap in the LaX 3 :Ce 3+ (X=F, Cl, Br, I) series and hence a potentially higher scintillation yield. The luminescence properties of LaI 3 :Ce were investigated by means of optical, X-ray, and g-ray excitation. Unexpectedly, the compound is a poor scintillator at roo

## Abstract Ce^3+^‐doped oxide glass with high Gd~2~O~3~ (30 mol%) concentration was prepared as a scintillating glass under CO reducing atmosphere. A dominant emission band of the Ce^3+^ 5d → 4f transition peaking around 400 nm was observed in the photo‐ and radioluminescence (PL, RL) spectra. PL
