Photostimulated luminescence (PSL) is observed in BaBrCl: Eu^2+after X-ray irradiation at room temperature. It is suggested by PSL stimulation spectrum and difference absorption spectrum (DAS) that F centers are formed upon X-ray irradiation and both spectra show two bands which are centered at about 550 nm and 675 nm respectively. This enables the use of semiconductor light-emitting diodes (LED) instead of gas lasers for photostimulation. The PSL intensity increases linearly with X-ray irradiation dose increasing, and the conversion efficiency is 29% that for the standard commercial storage phosphor BaFBr:Eu from Fuji imaging plate.
