英文摘要	A gamma-ray irradiation-assisted polyacrylamide gel method has been used to synthesize MgAl2O4:Ce and Mn-codoped MgAl2O4:Ce phosphors. Ce ion doping improved the photoluminescence properties of MgAl2O4 but did not change the cubic spinel structure of the host. Transmission electron microscopy showed that the mean particle size of the Ce- and Mn-codoped MgAl2O4 nanoparticles was smaller than that of the MgAl2O4 nanoparticles. Ce and Mn codoping improved the light absorption capacity and utilization, the separation efficiency of photogenerated carriers, and the photocatalytic activity of the MgAl2O4 nanoparticles. The MgAl2O4:Ce:Mn nanoparticles exhibited high photocatalytic activity for photodegradation of methylene blue dye under simulated sunlight irradiation due to the synergistic effects of the band-edge position, the light absorption capacity and utilization, and the separation efficiency of photogenerated carriers.
