Radiation image storage panel

摘要

A radiation image storage panel composed of a substrate and a phosphor film of an europium activated cesium bromide phosphor containing an europium element at an atomic ratio in the range of 0.0001 to 0.01 in terms of Eu/Cs and having been formed by vapor deposition shows specifically high sensitivity. The phosphor film is favorably deposited on the substrate by electron beam-evaporation method using plural evaporation sources.
