SrI 2 : a novel scintillator crystal for nuclear isotope identifiers

Abstract

The growth and scintillating properties of undoped and Eu²⁺ doped Strontium Iodide indicate excellent potential for gamma ray spectroscopy. Energy resolution at 662 keV 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.
