Radiation image storage panel and process for producing the same

摘要: A radiation image storage panel comprises a layer containing an europium activated cesium bromide stimulable phosphor. The phosphor has structure such that ratio of signal intensity, which corresponds to g=1.90 with respect and is taken in ESR spectrum at Q-band, the g=1.88 equal least 0.7. produced process, wherein vapor phase deposited film, contains pillar-shaped crystals phosphor, formed on base plate vacuum atmosphere then subjected heat processing atmosphere.
