Abstract
Intense photostimulated luminescence (PSL) is observed, for the first time, in x-ray irradiated europium-doped potassium chloride (KCL:Eu) single crystals. The intensity of PSL with a peak at about 420 nm, which is emitted by stimulation with 560 nm light, is proportional to the optical density of the F centers, which are created by x-ray irradiation, over the wide range of the x-ray absorbed dose. This suggests that KCl:Eu is one of the most attractive candidates for a two-dimensional x-ray imaging sensor utilizing the PSL phenomenon.
