Abstract:

The search for superior nuclear radiation detection materials is ongoing. Current scintillator materials using Thallium doped Sodium Iodide or Cesium Iodide are the benchmarks for ease of use and quick identification of isotope species. This research aims to explore Cesium Bromide doped with 1 molar tin CsBrSn-1 and Cesium Tin Bromide CsSnBr3 as candidate materials for a new scintillator. The techniques of Extended X-Ray Absorption Fine Structure EXAFS, X-Ray Absorption Near Edge Structure XANES and Cathodoluminescence are used to determine the suitability of CsSnBr3 and CsBrSn 1 with Sn4 as a potential scintilator materials and explore their crystal and electronic structures. Comparisons with current published work by Savchyn et al. 2007 on CsSnBr3 and CsBrSn-1 with Sn2 will be made. Cathodoluminescence shows the CsBrSn-1 with Sn4 to luminesce at 2.4-eV and 3.0-eV, green and violet respectively, indicating the strong possibility of using CsBrSn-1 as a scintillator.
