Abstract

Nanosized BaHfO₃:Ce phosphors were prepared through a nitrate-citrate combustion process at low temperatures, and the optimal temperature is about 300 °C. The combustion-synthesized powders are uniform and in good dispersion with average particle size of about 55 nm. Broad emission band centered at 387 nm, characteristic of 5d → 4f transitions of Ce ³⁺, was observed for BaHfO₃:Ce nanocrystals under UV excitation. The relative density of the BaHfO₃:Ce ceramics sintered at 1850 °C for 12 h in H₂ atmosphere could reach ∼98%.
