Abstract

The luminance and the lifetime of new cathode-ray projection tubes, formed by YAG single crystal faceplates deposited with P53 or P53(Ga) phosphor powder, is investigated in this paper. Since the YAG faceplates have high thermal conductivity, the tubes can operate at high power density for long time. The experiments demonstrated that the lifetime of the YAG tubes have reached several thousands hours at high intensity. The cathodoluminescent efficiency of P53(Ga) phosphor is higher than that of P53 phosphor, but the maintenance of P53 phosphor is better.
