Methods of producing yttrium-aluminium-garnet fine particles and yttrium-aluminium-garnet based phosphor fine particles

摘要

Methods of producing fine, single-phase YAG particles and fine, single-phase YAG phosphor particles includes subjecting yttrium and aluminium solubilized in an aqueous alkaline solution of pH not less than 10.0 to heating at not lower than 270oC to produce fine single-phase YAG particles. The methods also include adding terbium solubilized in an aqueous alkaline solution as an activating element to the solution of yttrium and aluminium and subjecting this solution to heating to produce fine single-phase YAG phosphor particles.
