ABSTRACT:
The preparation of an amorphous gel of a hydrated oxide is coupled with the technique of controlled seeding to obtain monosize crystallized particles. Crystalline oxide particles, such as phosphors, are formed by a method comprising: (a) selecting an oxide system; (b) forming an amorphous phase of the oxide system; (c) controllably forming nuclei in the amorphous phase; and (d) converting the amorphous phase to the crystalline oxide particles by growth of the nuclei. The oxide particles have a substantially single size, with a narrow size distribution.
