Radiation image conversion panel and preparation method thereof

A method for manufacturing a radiation image conversion panel comprising a support having thereon a stimulable phosphor layer;

• the method comprising the steps of:
• (i) forming the stimulable phosphor layer of a thickness of not less than 50 μm on the support via vapor deposition;
• and
• (ii) conducting a process of heating the phosphor panel having the stimulable phosphor layer, so as to have the ratio of transmittance T/T0 at a stimulated luminescence wavelength of a stimulable phosphor being 0.5≦T/T0≦10.
