Abstract

Imaging plates have been fabricated with SrCl2:Eu2+, Na+ photostimulable phosphor and the photostimulated luminescence (PSL) properties of the plates have been tested for digital radiography. The PSL spectrum of the imaging plate shows a broad band peaking at 407 nm with a half-width of 16.6 nm. The imaging plate exhibits linear dependence on dose in the range of 0.2 mGy ~ 10 Gy. The PSL intensity of the imaging plate fades by approximately 40 % after 120 minutes at room temperature. The spatial resolution of the imaging plate is about 2.0 lp/mm. We obtained clear X-ray radiograph of a computer mouse and a electric bulb from our imaging plate.
