Abstract: A method for producing a photostimulable phosphor represented by a following General Formula (1), includes subjecting phosphor particles in the photostimulable phosphor to a surface treatment by using a fluorine-containing compound after calcining the phosphor particles: General Formula (1), (Ba1-x M1) FBryI1-y X:aM2, bLn, cO wherein M1 is at least one alkaline earth metal atom selected from Mg, Ca, Sr, Zn and Cd; M2 is at least one alkaline metal atom selected from Li, Na, K, Rb and Cs; X is at least one halogen atom selected from Cl, Brand I; Ln is at least one rare earth atom selected from Ce, Pr, Sm, Eu, Gd, Tb, Tm, Dy, Ho, Nd, Er and Yb; and x, y, a, b and c are numbers within the range of 0≦x≦0.3, 0≦y≦0.3, 0≦a≦0.05, 0<b≦0.2 and 0<c≦0.1, respectively.

Abstract: A preparation process of a stimulable phosphor which exhibits no deterioration in radiographic performance due to moisture absorption and are usable in a viable state over a long period of time is disclosed, wherein after subjected to calcination, phosphor particles are coated with a fluorine-containing compound and a silane coupling agent. A radiation image conversion panel containing the stimulable phosphor is also disclosed.
