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.
