ABSTRACT:
A method for coating moisture sensitive inorganic particles, such as phosphors, comprising mixing the inorganic particles having a particle size of about 1 to 100 micrometers with nanometer-sized coating particles, and firing the mixture to soften or melt the nanometer-sized particles about the inorganic particles, forming a moisture impervious coating. The coated particles are washed to remove excess particles, and dried. Coated moisture sensitive phosphor particles are impervious to moisture.
