摘　　要：Photostimulated luminescence was observed in X-ray irradiated BaBrCl doped with Eu^2 ＋ . It shows an emission band that peak at 413 nm, and two difference absorption spectra （DAS） bands that peak at - 550 nm and 675 nm respectively. The stimulation energy is lower than that of BaFX：Eu^2＋ （X = Cl, Br）, and matches the cheaper, more portable, and more convenient semiconductor laser better. The results indicate that BaBrCl ： Eu^2＋ shows positive potential as a promising X-ray storage phosphor for practical utilization.Photostimulated luminescence was observed in X-ray irradiated BaBrCl doped with Eu^2 ＋ .
