Development of Phase‐Separated Scintillators with Light‐Guiding Properties

Abstract

Alkali halide systems that function as phase-separated scintillators (PSSs) with light-guiding properties are sucessfully created. Furthermore, it is the matrix phases of the PSSs which display the light-guiding properties. CsI–NaCl:Tl is a practical material pair because of its high pixel light output and good spatial resolution.
