Process for manufacture of radiation image storage panel

摘要

A radiation image storage panel is manufactured by the steps of heating and vaporizing an evaporation source comprising a phosphor or its starting materials and depositing the vaporized phosphor or materials on a substrate to form a phosphor layer in an evaporation-deposition apparatus, in which the steps are carried out at a pressure of 0.05 to 10 Pa and under the following condition: 0.3<=(T-S)/MFP<=300 in which MFP stands for a mean free path (unit:meter) of the vaporized phosphor or materials, and T-S stands for a space (unit:meter) between the evaporation source and the substrate.
