Abstract

Y2O3 ∶ Eu3+ phosphor particles were obtained by calcination of composite Y–Eu oxalate particles prepared in emulsion liquid membrane (ELM, water-in-oil-in-water (W/O/W) emulsion) systems. In the ELM systems, composite Y–Eu particles could be prepared by transporting either Y3+ and Eu3+ ions or oxalate ions from the external water phase into the internal water phase, employing proper ELM systems, where bis(1,1,3,3-tetramethylbutyl)phosphinic acid (DTMBPA) or 2-methyl-2-ethylheptanoic acid (VA-10) was used as an extractant (cation carrier), or tri-n-octylamine (TNOA) was used as an anion carrier. These ELM systems were effective for preparing size (submicrometer) and morphology (spherical) controlled composite Y–Eu oxalate particles in the internal water droplets. The Y2O3 ∶ Eu3+ particles obtained by calcination of the composite oxalate particles showed photoluminescence at 614 nm.
