<p>A process for producing a scintillator including the steps of producing a CsI columnar film formed of columnar CsI crystals by a deposition method, and adding an emission center to the CsI columnar film by disposing the CsI columnar film and an emission center material in a non-contact state in a closed space, heating the CsI columnar film in the range of not less than a sublimation temperature or evaporation temperature of the emission center material and not more than a temperature at which a columnar shape of the CsI columnar film can be maintained, and heating the emission center material at a temperature of not less than a sublimation temperature or evaporation temperature thereof.</p> |
