Abstract : By the use of careful phosphor engineering, new synthetic processes and optimised coating techniques, a range of improved and novel phosphor systems have been developed. These phosphors were designed for cathode ray application, more particularly for low voltage FED use. Improvements include the reduction in particle size to an average of 3 to 1 micrometers for higher resolution, a new saturated blue low voltage system based on bismuth activated yttrium niobate, and a bright saturated red phosphor barium zinc sulphide manganese. These phosphors were supplied to many US national laboratories and industrial enterprises.
