Effect of Ce on radiation damage of Gd2O2S: Pr ceramics scintillator
Description
For improvement of the image quality of X-ray CT, X-ray detector requires more sensitive and low afterglow scintillator. In order to realize the requirements, Gd2O2S: Pr ceramics scintillator which has a light output of 1.8 times of CdWO4 is now in practical use. Ce doped in the Gd2O2S: Pr ceramics scintillator is effective for reducing undesirable afterglow. The effect of Ce on the radiation damage was studied in this paper. The radiation damage decreased with increase in Ce content. It was considered that Ce reduced the color centers and traps. (author)
