ABSTRACT:
A variable color cathodoluminescent manganese activated zinc silicate phosphor is disclosed. The zinc silicate host is modified by the addition of small amounts of aluminum and phosphorus. Variation in the current density of the cathode ray excitation produces emission varying from green to blue. The method of making the phosphor and a cathode ray tube device employing the phosphor is also disclosed.
