The cubic nano-structured HfO2-Sc2O3:Eu3+ were successfully synthesized via a combustion process. Phase evolution of the synthesized powders was determined by X-ray diffraction measurements. Pure cubic phase of HfO2-Sc2O3 solid solution was obtained after being calcined at 800 degrees C for 2 h.The particle size and morphology were analyzed by TEM. The luminescence properties were also investigated. Photoluminescence spectra of Eu3+ doped HfO2-Sc2O3 nano-powders showed red emission at 613 nm which corresponds to the 5D0-7F2 transition of Eu3+ ion.
