Abstract
The use of rare earth oxysulfide-type phosphor screens is common place within x-ray scanning instrumentation either in detection or imaging mode. The x-ray phosphors based on praseodymium-doped gadolinium oxysulfide (Gd2O2S:Pr) have short decay times to 10% intensity compared to the more well known europium and terbium analogues. The prompt emission of 511 nm luminescence from the Pr-ion results in excellent capability for fast scanning x-ray applications in the 20 - 100 microsecond(s) time frame.
