Title: Lu1-xI3:Cex—a scintillator for gamma ray spectroscopy and time-of-flight PET

Abstract

The present invention concerns very fast scintillator materials comprising lutetium iodide doped with Cerium (Lu1-xI3:Cex; LuI3:Ce). The LuI3 scintillator material has surprisingly good characteristics including high light output, high gamma ray stopping efficiency, fast response, low cost, good proportionality, and minimal afterglow that the material is useful for gamma ray spectroscopy, medical imaging, nuclear and high energy physics research, diffraction, non-destructive testing, nuclear treaty verification and safeguards, and geological exploration. The timing resolution of the scintillators of the present invention provide compositions capable of resolving the position of an annihilation event within a portion of a human body cross-section.
