摘要：

The current work describes two new Eu2+-activated scintillator materials, CsCal(3):Eu and CsCaCl3:Eu. Single crystals of CsCal(3):Eu and CsCaCl3:Eu were grown from the melt via the vertical Bridgman method. Scintillation properties, including decay time, light output, X-ray excited luminescence and light output, as a function of excitation energy were measured, as were the photoluminescence emission and excitation spectra. In addition, moisture sensitivity was evaluated by measuring the moisture uptake rate and compared with those of Nal: Tl and Cs2LiYCl6:Ce reference scintillators. (c) 2012 Elsevier B.V.
