摘要：

Eu3+ doped-Y2Hf7O17 nanopowders were synthesized by the chemical self-combustion method at low temperature. X-ray diffraction, transmission electron microscopy, and scanning electron microscopy were employed to analyze the phase composition and the characteristics of the nanopowders. The excitation and emission spectra were analyzed with a fluorescence photometer. Results show that nanoscale powders calcined at 800 degrees C have good luminescent properties. There are two peaks in the emission spectra. One is at 595 nm, and the other is at 614 nm. Analysis of X-ray diffraction and photoluminescence spectra reveals that Y2Hf7O17 is cubic phase. The sample doped with 14 mol% Eu3+ has the maximum luminescent intensity.
