| description | A method for eliminating carbonaceous contaminants and preventing the hydration/solubilization of the oxide coating of a phosphor is described. The method involves the annealing of the oxide coated phosphor at a temperature and for a period sufficient to preclude adversely affecting the protective oxide coating on the phosphor during subsequent water-based suspension processing without detrimentally altering the phosphor. After annealing the phosphor is cooled and then added to a water-based suspension. The optimum conditions for annealing a manganese activated zinc silicate phosphor or a calcium halophosphate phosphor having a protective aluminum oxide coating are the combination of a temperature between about 700.degree.C and about 850.degree.C and for a period of time from about 15 minutes to about 20 hours. |
