Development of color centers in calcium fluorophosphate under the influence of x-ray and electron irradiation

Multi-Photon Phosphor Feasibility Research

“…For the case of halophosphate , the brightness of luminescence decreases up to 20% (depending on the duration of grinding) with the dislocation density increasing from 10 8 to 10 10 cm -2 [69]. The reasons for this can be multiple, starting from adding sites for ion-electron (or electron-hole) recombination to gaining higher surface area that has a lowered threshold for radiation damage.…”
