Patent ID: 7422765

Claim:
Method for producing a binderless CsBr:Eu storage phosphor screen comprising steps of: combining CsBr and EuOBr as phosphor precursors for an alkali metal storage phosphor; and vacuum depositing said combination of phosphor precursors on a substrate, wherein during said step of vacuum depositing said substrate is kept at a temperature T, such that 50° C.≦T≦300° C. and said vacuum deposition proceeds in an Ar-atmosphere with an Ar-pressure of at most 3 Pa; and wherein said storage phosphor screen shows an XRD-spectrum with a (100) diffraction line having an intensity I 100 and a (110) diffraction line having an intensity I 110 , so that I 100 /I 110 ≧1, when said XRD-spectrum is measured according to TEST A.
