ABSTRACT:
A method for forming a low-energy electron excited fluorescent screen. First, there is dissolved in a non-aqueous solvent a charging material. The charging material when dissolved forms a cation which is susceptible to forming an oxide, which oxide is a first essential component of a low-energy electron excited fluorescent phosphor composition. In addition to the charging material, there is suspended in the non-aqueous solvent a phosphor which naturally adopts a positive charge in the non-aqueous solvent. The phosphor is a second essential component of the low-energy electron excited fluorescent phosphor composition. There is then electrophoretically deposited from the non-aqueous solvent the cation and the phosphor to form a low-energy electron excited fluorescent phosphor precursor composition. The electrophoretic deposition occurs upon a fluorescent screen substrate which serves as a cathode. Finally, the low-energy electron excited fluorescent phosphor precursor composition is dried to form a low-energy electron excited fluorescent phosphor composition upon the fluorescent screen substrate.
