Abstract:
The features of the growth of alkaline-earth halide crystals BaBrI, BaClI and SrBrI by the Bridgman method are considered. The results of the study of the scintillation characteristics of grown crystals activated by europium ions are given. The actual content of europium in crystals was determined, and the light yield and luminescence decay times were estimated, and the X-ray luminescence spectra and absorption spectra of the obtained crystals were given.
The work in the part of studying spectroscopy and optical properties of obtained crystals, the concentration of europium in the crystals and the analysis of the obtained results was supported by the Russian Science Foundation, grant RSF 18-72-10085. The crystal growth and the measurement of the X-ray luminescence spectra were carried out in the framework of the state task 0350-2016-0024.
