摘要: A radiographic image conversion screen comprising a support, a first fluorescent layer formed on the support and consisting essentially of a blue emitting phosphor and a second fluorescent layer formed on the first fluorescent layer and consisting essentially of a green emitting rare earth oxysulfide phosphor. The green emitting rare earth oxysulfide phosphor is represented by the formula: (Ln.sub.1-i, Y.sub.i, Tb.sub.a, R.sub.b).sub.2 O.sub.2 S where Ln is at least one element selected from the group consisting of La, Gd and Lu, R is at least one element selected from the group consisting of Dy, Pr, Yb and Nd, and i, a and b are numbers within the ranges of 0.ltoreq.i.ltoreq.0.35, 0.0005.ltoreq.a.ltoreq.0.09 and 0.0002.ltoreq.b.ltoreq.0.01, respectively.
