摘要： A phosphor composition selected from a range of phosphor compositions is provided for discharging spent electrons from a display screen of a luminescent display. The selected phosphor composition is a mixture of phosphor species, including a dielectric phosphor species capable of emitting visible green, blue or red light when subjected to excitation electrons at a relatively high voltage and a conductive phosphor species capable of emitting visible green, blue or red light when subjected to energized excitation electrons at a relatively low voltage. The display screen of the luminescent display is coated with the selected phosphor composition to form a cathodoluminescent layer on the screen. The cathodoluminescent layer is then selectively subjected to excitation electrons having a voltage within a predetermined broad range. The excitation electrons impart their energy to the phosphor composition causing it to emit visible green, blue or red light, thereby creating an image on the screen. The conductive phosphor species of the phosphor composition subsequently conducts the resulting spent electrons to the anode of the screen where the spent electrons are discharged.
