MgAl2O4 and MgAl2O4:Ce phosphors were successfully synthesized through a gamma-ray irradiation assisted polyacrylamide gel route.The crystal structure,surface morphology,optical and photoluminescence properties of MgAl2O4:Ce phosphors were studied by X-ray powder diffraction（XRD）,transmission electron microscopy（TEM）,ultraviolet-visible spectrophotometer and fluorescence spectrophotometer.Based on the experimental results,the photoluminescence mechanism of nanoscale MgAl2O4:Ce phosphors was analyzed.Experiment result showed that the crystallization temperature of MgAl2O4 and MgAl2O4:Ce phosphors synthesized by a gamma-ray irradiation assisted polyacrylamide gel route was lower about 100 ℃ than that of the conventional polyacrylamide gel route.The mean particle size of the MgAl2O4:Ce phosphor was 14 nm.Cerium doping MgAl2O4 decreased the particle size and Eg value,improved the colour and photoluminescence properties of MgAl2O4.Two blue emission peaks at 425 nm and 465 nm were observed for the MgAl2O4:Ce phosphor when the excitation peak was 275 nm.The impurity defect（Ce3+） played a crucial role in the luminescence process on the basis of the energy transfer mecha nism.The MgAl2O4:Ce phosphor can be used as a promising radiation resistance phosphor for space lighting field.
