摘要

A simple sol-combustion route involving EDTA was employed to prepare nanosized MHfO₃:Ce (M = Ba, Sr, or Ca) which were characterized by XRD, TEM and luminescent measurements. The as-prepared powders consist of particles with cube-like morphologies for Ce-doped BaHfO₃ and SrHfO₃ and uniform polyhedron-like morphology for Ce-doped CaHfO ₃. The average sizes of crystallites of BaHfO₃:Ce, SrHfO₃:Ce and CaHfO₃:Ce are 48, 34 and 30.4 nm, respectively. Broad emissions for nanocrystals of MHfO₃:Ce (M = Ba, Sr, or Ca) resulting from Ce³⁺ 5d → 4f transitions were observed under UV excitation, and the Stokes shift for nanocrystals of Ce-doped BaHfO₃, SrHfO₃ and CaHfO₃ are around 9000, 7400 and 7020 cm^-1, respectively.
