ZINC SULFIDE PHOSPHOR COACTIVATED WITH GOLD, COPPER AND ALUMINUM

摘要

ZINC SULFIDE PHOSPHOR COACTIVATED WITH GOLD, COPPER AND ALUMINUM The addition of gold as an activator to a zinc sulfide phosphor coactivated by copper and aluminum results in color coordinate shifts of cathodoluminescent emissions to higher x values, enabling use, for example, as a replacement for the zinc cadmium sulfide green phosphor activated by copper and aluminum presently used in color cathode ray tubes for color television.
