Abstract

Monodispersed BaAl2O4:Eu2+ nanospheres with 180 nm size were synthesized through forced hydrolysis using γ-Al2O3 nanospheres as a template followed by a subsequent heat treatment. The incorporation of a barium precursor onto an individual γ-Al2O3 template nanosphere was optimized by controlling the reaction time. The photoluminescence properties of the BaAl2O4:Eu2+ nanospheres were comparable to those of the bulk counterpart prepared at 1300 °C through a conventional solid-state reaction method.
