A photostimulable phosphor, wherein said phosphor is within the scope of the following empirical formula (A):

Photostimulable phosphor and radiation image recording and reproducing

A photostimulable phosphor of which the emission intensity at the stimulation wavelength of 550 nm is higher than the emission intensity at the stimulation wavelength of 600 nm, characterized in that said phosphor is a divalent europium activated barium fluorobromide containing as codopant samarium, and wherein the terminology barium fluorobromide stands for an empirical formula wherein (1) a minor part of the barium (less than 50 atom %) is replaced optionally by at least one metal selected from the group consisting of a monovalent alkali metal, a divalent alkaline earth metal other than barium, and a trivalent metal selected from the group consisting of Al, Ga, In, Tl, Sb, Bi, Y, and a rare earth metal selected from the group consisting of Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, (2) a minor part (less than 50 atom %) of the bromine is replaced by chlorine, and/or iodine, and (3) wherein fluorine is present stoichiometrically in a larger atom % than bromine taken alone or bromine combined with chlorine and/or iodine.
