Abstract:Hydrocarbonate-gel method was applied to prepare MgSrAl10O17:Eu2+ blue phosphors with quasi-spherical morphology Scanning electron microscope (SEM) and powder X-ray diffraction (XRD) were employed to characterize the resulting products. SEM image showed that the phosphor particles were of quasi-spherical shape with the diameter in the range of 1 similar to 3 mu m. X-ray diffraction patterns of the resulting samples displayed pure MgSrAl10O17 phase after annealed at 1270 degrees C for 3 h. The effects of annealing temperature, parameters on crystalline phase evolution and photoluminescence intensities of the resulting phosphor were also studied. Upon excitation with UV irradiation, MgSrAl10O17:Eu2+ shows a strong blue emission at 468 nm corresponding to 4f(6)5d(1) -> S-8(7/2) transition of Eu2+, which has potential applications in fluorescent lamps and plasma display panels.
