    摘要： Disclosed are a method for converting radiographic image which comprises the steps of:
    (a)storing radiation energy-corresponding to a radiographic image in a stimulable phosphor of a panel comprising a stimulable phosphor-containing layer. (b)scanning the layer with a stimulating ray to release the stored energy as a fluorescence, and (c)detecting the fluorescence to form an image, wherein the stimulable phosphor is represented by the following formula:

    wherein M represents either Cs or Rb; M' represents at least one of alkaline metals selected from the group consisting of Li, Na, K, Rb and Cs; M" represents at least one divalent metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn, Cd, Cu and Ni; M III represents at least one metal selected from the group consisting of Se, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Cd, Tb, Dy, Ho, Er, Tm, Yb, Lu, AI, Ga and In; A represents at least one metal oxide selected from the group consisting of BeO, MgO, CaO, SrO, BaO, ZnO, Al 2 O 3 , Y 2 0 3 , La 2 0 3 , In 2 O 3 , SiO 2 , Ti02 , Ge02 , SnO 2 , Nb 2 0 5. Ta 2 0 5 and Th0 2 ; B represents at least one metal selected from the group consisting of Eu, Tb, Ce, Tm, Dy, Pr, Ho, Nd, Yb, Er, Gd, Lu, Sm, Y, TI, Na, Ag, Cu, Mg, Pb, Bi, Mn, and In; X, X' and X" each may by the same or different and represent a halogen atom selected from F, C, Br and I; x, a, b, c and d are numerals in the range of O ≦x ≦ 1,0≦a≦ 1,0≦ b≦ 0.5, 0 - c 0.5 and 0 The radiation energy storage panel using the present stimulable phosphor is superior in water vapor resistance to the panel using the prior art stimulable phosphor and can greatly improve lowering in stimulable emission luminance with lapse of time.
