Photostimulated luminescence phenomenon was observed in a fluoroaluminate glass doped withEu2+.When the x-ray irradiated glass was excited by a He–Ne laser (633 nm), photostimulated luminescence at 400 nm due to the5d–4ftransition ofEu2+ions was observed. X-ray absorption spectra showed that a part ofEu2+converted toEu3+upon the irradiation of x-ray. By comparing with the investigations on photostimulable luminescence phosphorBaFBr:Eu2+,the luminescence appears to result from the photostimulated recombination of holes and electrons at traps, which leave electrons in a long-lived excited state. ©1997 American Institute of Physics.
