Process for preparing rare earth activated alkaline earth metal fluorohalide stimulable phosphor particles

A method for preparing a stimulable phosphor is disclosed, comprising forming a stimulable phosphor and coating the formed stimulable phosphor with a metal oxide and a silane coupling agent, or a metal oxide and a metal alkoxide. Another method is also disclosed, comprising forming a stimulable phosphor precursor, calcining the formed precursor in the presence of a metal oxide or metal alkoxide, and coating the calcined precursor with a silane coupling agent or metal alkoxide. Further disclosed is a preparation method of a radiation image conversion panel containing the stimulable phosphor.

Stimulable phosphor and radiation image conversion panel by use thereof

A preparation method of an oxygen-introduced stimulable phosphor including a rare earth activated alkaline earth metal fluorohalide stimulable phosphor is disclosed, comprising the steps of heating a precursor of a stimulable phosphor in an atmosphere containing oxygen, and further heating the heated precursor in a weakly reducing atmosphere. Stimulable phosphors prepared by this method and a radiation image conversion panel by use thereof are also disclosed.
