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.

Radiographic phosphor panel having both binder compatible oxosulfur

A method, a storage phosphor prepared by the method, and a storage panel. In the method, a precursor mixture is fired, at a temperature between 700.degree. C. and the melting point of the phosphor, to produce an intermediate product. The precursor mixture comprises a combination of species characterized by the relationship:

Annealed alkaline earth metal fluorohalide storage phosphor, preparation

A radiographic image storage phosphor, stabilized intermediate, and methods for preparing storage phosphor, and stabilized intermediate. The storage phosphor is the product of firing a combination of species characterized by the relationship:

Stabilized phosphor intermediates, storage phosphors, radiation image

A radiation image storage phosphor; a composition of matter including the storage phosphor and a stabilizer for iodine; and a radiation image storage panel including the inventive phosphor. The storage phosphor has a combination of species characterized by the relationship:

Alkaline earth metal fluorobromoiodide storage phosphor, and radiation

A radiographic phosphor panel having binder compatible oxosulfur stabilizer and a preparation method. The phosphor panel has a support and a luminescent layer overlaying the support. The luminescent layer includes phosphor crystals, binder and an oxosulfur reducing agent. The oxosulfur reducing agent is dispersed within the luminescent layer on a substantially molecular basis. The oxosulfur reducing agent is a reducing agent for iodine. The oxosulfur reducing agent has a concentration sufficient to substantially increase the photostimulated luminescence of the panel.
