Photostimulated Luminescence in KCl_xBr_1-x: Eu Phosphor Ceramics as a two-Dimensional Image Sensor Material for Ionizing Radiation

摘要

Intense Photostimulated Luminescence (PSL) is observed, for the first time, in X-ray-irradiated KCl_XBr_1-x: Eu phosphor ceramics. The peak in the stimulation spectrum for PSL red-shift with increasing the Br content of KCl_xBr_1-x: Eu phosphor. The intensity of PSL with a peak at about 420 nm increaseslinearly with increasing X-ray dose over the wide range.
