Luminescent Performances of Pure CsI Crystals

Shen Dingzhon

Abstract

The optical transmission, X-ray excited emission, energy spectra and decay time characteristics were measured for pure CsI crystals grown by Stockbarger process. The results show thatthe crystals has two scintillation components: a fast component peaked at 310um with 40nsdecay time and a slow component at 450um with~2.4μs. The slow emission intensity is not stableand considerably thectcd by I- vacancy defects in the crystal. The intensity ratio of fast to slowcomponent obtAlNed is 91.8%.
