Abstract :
Two rare earth materials, La2O2S:Tb and Gd2O2S:Tb, have significant potential as inputscreen phosphors for x-ray image intensifier use. These materials exhibit high luminescent efficiencies and high x-ray absorption. In this paper we present a detailed discussion of the properties of these new phosphors and suggestions for further improving their performance in image intensifier tubes.
