Abstract:
A method for the production of oxygen-containing phosphor particles, comprising the steps of:a) generating an aerosol of droplets from a liquid wherein said liquid comprises a oxygen-containing phosphor precursor and wherein said droplets have a size distribution such that at least about 80 weight percent of said droplets have a size of from about 1 &mgr;m to about 5 &mgr;m; b) moving said droplets in a carrier gas; c) heating said droplets to remove liquid therefrom and form oxygen-containing phosphor particles; and d) annealing said oxygen-containing phosphor particles to increase the crystallinity of said phosphor particles.
