Abstract High-purity ultrafine MgAl2O4 powder was synthesized by metal-alkoxide method and calcining for 2~4 h.And then MgAl2O4/Ce∶YAG tra nsparent ceramics were fabricated by hot-pressed sintering and hot isostatic pressed sintering technique with YAG∶Ce powder and MgAl2O4 powder. The tra nsparent ceramics were characterized by XRD, SEM, EDS and fluorescence spectrometer, respectively. The results show that the crystal phase of the tra nsparent ceramic was composed of MgAl2O4 and YAG,and the YAG phase dispersed well in the matrix of MgAl2O4. The excitation spectra had a weak band at 345 nm and a strong band at 475 nm. The broad emission peaks at about 533 nm were attributed to 5d→4f tra nsition of Ce3+ io ns. Decay curves for the fluorescence of MgAl2O4/Ce∶YAG tra nsparent ceramic test show that the lifetime of the Ce∶YAG glass ceramic was 59.74 ns. All results show that MgAl2O4/Ce∶YAG tra nsparent ceramic may be a promising fluorescent material for white LED applicatio ns.
