Patent ID: 7601385

Claim:
A method for manufacturing a radiation image conversion panel comprising a phosphor panel, said phosphor panel comprising a support having a stimulable phosphor layer thereon; the method comprising: (i) producing the phosphor panel via a process comprising vapor depositing the stimulable phosphor layer on the support, the stimulable phosphor layer having a thickness of not less than 50 μm, and containing at least one stimulable phosphor; (ii)soaking the phosphor panel in a halogenated solvent; and (iii) heating the phosphor panel after said soaking; wherein a ratio of transmittance T/T 0 at a stimulated luminescence wavelength of the at least one stimulable phosphor is 0.5≦T/T≦10, provided that—T represents transmittance after said heating, and T 0 represents transmittance before said heating.
