  • Method for annealing phosphors applied to surfaces having melting points below the annealing temperature of the phosphor
    Patent number: 5234484
    Abstract: A method for annealing a deposited material on a substrate structure, where the annealing temperature of the deposited material is greater than the melting temperature of the substrate structure, including the step of inserting the substrate structure into an oven preheated to a temperature above the annealing temperature. The substrate structure is kept in the oven for a time interval wherein the mean temperature of the deposited material is above the annealing temperature and the mean temperature of the substrate structure is below its melting temperature. The substrate structure may be actively cooled while in the oven, thus increasing the time interval the mean temperature of the deposited material can be maintained above the annealing temperature.
