A blue‐emitting ZnS: Ag, Al phosphor with low defect density has been developed successfully for projection CRTs. Good crystallinity was verified by cross‐sectional transmission electron microscopy. As a result, higher luminescence efficiency, good linearity, and longer luminescence lifetime are obtained in 7‐inch projection CRTs.
