Abstract
The features of using the Bridgman method for growing alkaline earth halides crystals BaBrI, BaClI, and SrBrI are discussed. The results of the study of scintillation characteristics of grown crystals activated by europium ions are presented. The actual content of europium in crystals is determined and the values of the luminescence yield and decay time are estimated. X-ray luminescence and absorption spectra of the obtained crystals are given.
