PRODUCTION OF FINE PARTICLE OF YTTRIUM-ALUMINUM-GRANET AND FINE PARTICLE OF YTTRIUM-ALUMINUM-GARNET PHOSPHOR

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 270C to produce fine single-phase YAG particles. The methods...

More Information
Summary: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 270C 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.
