Abstract
Phosphor-containing panels or screens have improved resistance to yellowing and image defects by the incorporation of a primary or secondary amine having a pKa of 8.5 or more and a molecular weight of less than 10,000 daltons into the phosphor layer or an overcoat layer. A peroxide scavenger can also be present to further improve stability of the phosphor panel. The phosphors are preferably storage phosphors containing iodine. This phosphor panels can be prepared using non-peroxide-generating organic solvents for further stabilization.
