SrI_2, a Novel Scintillator Crystal for Nuclear Isotope Identifiers

摘要

The growth and scintillating properties of undoped and Eu~(2+) doped Strontium Iodide indicate excellent potential for gamma ray spectroscopy. Energy resolution at 662keV was found to be as good as 2.7% at 662 keV. The effect of purification by zone refining was also studied and crystal growth of SrI2 by the Bridgman technique was found to be less subject to cracking compared to the growth of lanthanum halide scintillators.
