Abstract

The scintillation properties of KMgF/sub 3/, KYF/sub 4/:Rb, K/sub 2/YF/sub 5/, KLuF/sub 4/, RbMgF/sub 3/, KZnF/sub 3/, BaTm/sub 2/F/sub 8/, LiYF/sub 4/:Nd, and BaF/sub 2/:Rb have been studied. The scintillation light output of these crystals was estimated from the X-ray induced emission spectra. Optical absorption spectra and decay time spectra were also measured and are presented. The first four crystals produce cross luminescence (CL) with a decay time of about 1.5 ns. CL was not observed for the other crystals.<>
