Gadorinium oxysulfide phosphor for digital radiography, radiographic image conversion screen and radiograph-forming device

摘要

A gadolinium oxysulfide phosphor for digital radiography represented by the following compositional formula, which mainly emits a green luminescence under excitation with radiation:wherein x, y and z are numbers which satisfy 1.2x10<-3><=x<=1.9X10<-2>, 5x10<-4><=Y&LE;19X10<-2 >and 10<-8><=Z&LE;8X10<-7>, respectively.
