摘    要:
Electron trapping materials(ETMs)have shownpromise in optical storage.The doubly or multi rare-earth doped alkaline-earth sulfides are a class of sti m-ulatable phosphors,which are expected to be used inthe field of optical Parallel Boolean operation,erasable and re-writable optical memory[1~3].In addition,BaFX∶Eu2+(X=Cl,Br)phosphor,which exhibits photo-sti mulated luminescence(PSL)and offers an alternative to conventional X-rayi magingtechnology to increase the i mage definition anddec…

关 键 词:BaFCl∶Eu~(2+)  photostimulated luminescence  color centre  electron trapping  rare earths
