In this paper, AlON phosphors doped with Ce3+ are prepared by solid-state reaction method. Phases, microstructures and optical properties of the synthesized phosphors are characterized by X-ray diffraction and scanning electron microscopy and photoluminescence. The results indicate that AlON3+:Ce phosphors emit the blue light centered at 390 nm under the excitation of 305 nm. The emission intensity of AlON:Ce3+ at 150 ℃ is about 86% of that measured at room temperature. It demonstrates that the AlON:Ce3+ has a great potential in applications of high-density white light-emitting diodes.
