Photostimulable phosphor for use in radiography |
| 摘要 |
A photostimulable rare earth metal doped barium strontium fluoride phosphor, characterized in that said phosphor is within the scope of following empirical formula (I): Ba1-xSrxF2-a-bBraXb:zA wherein: X is at least one member selected from the group consisting of Cl and I; x is in the range 0.06</=x</=0.50; a is in the range 0.75</=a</=0.96; b is in the range 0</=b<0.15; z is in the range 10-7<z</=0.15, and A is Eu2+ and wherein fluorine is present stoichiometrically in said phosphor in a larger atom % than bromine taken alone or bromine combined with chlorine and/or iodine.
