Development of accurate two-dimensional dose-imaging detectors using atomic-scale color centers in Ag-activated phosphate glass and LiF thin films

Novel disk-type X-ray two-dimensional (2D) imaging detectors have been developed by utilising atomic-scale defects as minimum luminescent units such as radiation-induced Ag-related species in Ag-activated phosphate glass and F-aggregated centres in lithium fluoride (LiF) thin films. Such luminescent...

description	Novel disk-type X-ray two-dimensional (2D) imaging detectors have been developed by utilising atomic-scale defects as minimum luminescent units such as radiation-induced Ag-related species in Ag-activated phosphate glass and F-aggregated centres in lithium fluoride (LiF) thin films. Such luminescent detectors are based on the radiophotoluminescence (RPL) and photoluminescence (PL) phenomena, respectively. Accurate accumulated 2D dose distributions with a high spatial resolution of micron order over large areas and a wide dynamic range covering 8 orders of magnitude were rapidly reconstructed and were successfully demonstrated for the first time by combining the Ag-doped glass with LiF thin films. These detectors should be suitable for X- and gamma-ray imaging in radiation diagnostics and clinical radiotherapy.
