A Scintillator Gd2 O 2 S : Pr , Ce , F for X‐Ray Computed Tomography

An efficient scintillator has been developed as a solid‐state detector for x‐ray computed tomography. Doping with halogen ions has improved the emission efficiency by 30% and doping with Ce reduces afterglow caused by traps in the host, . Hot isostatic pressing of this material in powder form with a trace of as a sintering aid, resulted in a translucent ceramic scintillator.
