EUROPIUM DOPED CAESIUM BROMO IODIDE SCINTILLATOR AND DETECTORS THEREOF WITH IMPROVED CONVERSION EFFICIENCY

A scintillator includes CsBrxI(1-x) doped with Europium (CsBrxI(1-x):Eu) wherein x<0.5, and is obtained by annealing CsBrxI(1-x):Eu material at a temperature from 50° C. to 280° C. The EPR spectrum of the obtained scintillator measured at room temperature at a frequency of 34 GHz shows a maximum...

More Information
Summary:A scintillator includes CsBrxI(1-x) doped with Europium (CsBrxI(1-x):Eu) wherein x<0.5, and is obtained by annealing CsBrxI(1-x):Eu material at a temperature from 50° C. to 280° C. The EPR spectrum of the obtained scintillator measured at room temperature at a frequency of 34 GHz shows a maximum signal height at a magnetic field of 1200 mT, and the signal height at 1090 mT and 1140 mT does not exceed 40%, wherein the normalized signal height percentage at 1200 mT is calculated to be 100%. The scintillator is useful in a high energy radiation detection and radiography imaging apparatus.
