Abstract

B-site-ordered double-perovskite oxide up-conversion phosphors La₂ZnTiO₆, La₂MgTiO₆, and Ba₂LaTaO₆ doped with Yb and Ho, Er, or Tm were synthesized by a citric acid complex gelation method and a polymerizable complex method. Under 980-nm excitation, the double-perovskite oxide phosphors doped with luminescent ions at the A-site (La₂ZnTiO₆ and La₂MgTiO₆) showed stronger up-conversion emission than the phosphor doped with luminescent ions at the B-site (Ba₂LaTaO₆). La₂ZnTiO₆ and La₂MgTiO₆, in which dopants occupied the A-site, showed different up-conversion emission behaviors because of structural distortion resulting from the substitution of B-site cations.
