Radiographic phosphor panel having both binder compatible oxosulfur stabilizer and oxosulfur pigment and method for preparing phosphor panel

摘要

A radiographic phosphor panel having both binder compatible oxosulfur reducing agent and oxosulfur reducing pigment, and a preparation method. The radiographic phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, binder, oxosulfur reducing agent, and oxosulfur reducing pigment. The phosphor crystals include iodine. The oxosulfur reducing agent is dispersed within the luminescent layer on a substantially molecular basis. The oxosulfur reducing pigment is dispersed within the layer as a particulate. The oxosulfur reducing agent and the oxosulfur reducing pigment are each a reducing agent for iodine. The oxosulfur reducing agent and the oxosulfur reducing pigment have a combined concentration sufficient to substantially increase the photostimulated luminescence of the panel.
