ABSTRACT:
A method of producing fine, single-phase YAG particles and fine, single-phase YAG phosphor particles. The method includes subjecting yttrium and aluminum solubilized in an aqueous alkaline solution to a heating reaction at not lower than a predetermined temperature to produce the fine single-phase YAG particles having a uniform particle size distribution. The method also includes adding terbium solubilized in an aqueous alkaline solution as an activating element to the solution of yttrium and aluminum and subjecting this solution to a heating section to produce fine single-phase YAG phosphor particles having a uniform particle size distribution.
