Single-crystal strontium iodide (SrI2) doped with relatively high levels (e.g., 3-6%) of Eu2+ exhibits characteristics that make this material superior, in a number of respects, to other scintillators that are currently used for radiation detection. Specifically, SrI2:Eu2+ has a light yield that is significantly higher than LaBr3:Ce3+-a currently employed commercial high-performance scintillator. Additionally, SrI2:Eu2+ is characterized by an energy resolution as high as 2.6% at the Cs-137 gamma-ray energy of 662 key, and there is no radioactive component in SrI2:Eu2+ unlike LaBr3:Ce3+ that contains La-138. The Ce3+-doped LaBr3 decay time is, however, faster (30 ns) than the 1.2 mu s decay time of SrI2:Eu2+. Due to the relatively low melting point of strontium iodide (similar to 515 degrees C), crystal growth can be carried out in quartz crucibles by the vertical Bridgman technique. Materials-processing and crystal-growth techniques that are specific to the Bridgman growth of europium-doped strontium iodide scintillators are described here. These techniques include the use of a porous quartz frit to physically filter the molten salt from a quartz antechamber into the Bridgman growth crucible and the use of a "bent" or "bulb" grain selector design to suppress multiple grain growth. Single crystals of SrI2:Eu2+ scintillators with good optical quality and scintillation characteristics have been grown in sizes up to 5.0 cm in diameter by applying these techniques. Other aspects of the SrI2:Eu2+ crystal-growth methods and of the still unresolved crystal-growth issues are described here. (c) 2013 Elsevier B.V. All rights reserved.
