The blue phosphor BaMgAl10O17 ： Eu^2＋ （BAM ： Eu^2＋） was prepared with microwave heating. The effects of synthesis temperature, heat preservation time and heating rate on the luminescent properties of BAM ： Eu^2＋ were studied by orthogonal tests. XRD results show that the blue phosphor BAM ： Eu^2＋prepared with microwave heating is hexagonal with the space group P63/mmc. The results from spectral analysis show that the peak wavelength of the sample is 450 nm,corresponding to Eu2＋ broadband transition 4f^65d→4f^7（^8S7/2）. And the chromaticity coordinates x and y are equal to 0. 146 3 and 0. 069 3 respectively. The relative brightness is 106.8%. The results from particle size analysis show that the center size Ds0 is 7.00 μm and particle size distribution is concentrated.
