Deterioration of photo-stimulated luminescence signals from materials by radiation

The Effect of Fast Kr Ion Irradiation on the Optical Absorption, Luminescence, and Raman Spectra of BaFBr Crystals

“…Eu 2+ doped BaFBr and many related storage phosphors have excellent properties and are most suitable for making various types of imaging plates consisting of phosphor powder dispersed in various organic binders. Image plates were originally developed for X-rays, but are now being extended to other types of ionizing radiation such as neutrons, gamma rays, and electron, proton, and even ion beams [1][2][3][4][5][6][7][8][9][10]. It is now clear that such materials have already found many interesting and indeed important applications in many areas of radiation imaging.…”

Characteristics of unerasable and reappearing photostimulated luminescence signals in over-irradiated imaging plates and a new complete erasing method

“…It is important to know the detailed characteristics of these effects on applied fields, which typically require establishment confidence, limitations, and a complete erasing. However, so far only two studies, which were reported by Kobayashi et al [6,7], have referred to these effects. These authors observed incomplete erasing and a self-generation of PSL signals in IPs after heavy irradiation by He + ions, but they did not further elucidate the characteristics and mechanisms of the effects.…”
