摘要： 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.
