Abstract:
1. A process for producing an evaporated phosphor sheet, comprising the steps of: introducing a carrier gas into a vacuum evaporation chamber; evaporating at least one film forming material from at least one evaporation source among plural evaporation sources; and depositing said at least one evaporated film forming material on at least one substrate in sheet form held within said vacuum evaporation chamber to form a stimulable phosphor layer, thereby producing said evaporated phosphor sheet having said stimulable phosphor layer formed on one substrate in sheet form, wherein said stimulable phosphor layer is formed with substantially all areas of the remainder of said plural evaporation sources except said at least one evaporation source being masked to block movement of heat toward said one substrate in sheet form.
