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.
