Europium ion doped BaMgAl10O17 blue phosphor nanopowder has been fabricated by urea–nitrate solution combustion synthesis at 590 °C for 5 min. These phosphors were codoped with different europium ion concentrations (1–8 mol%). The experimental results of x-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence showed that the phosphors have a hexagonal single phase structure, the average particle size of the powders was about 50 nm and the emission spectra have a broad band with maximum intensity at wavelength λmax=455 nm due to transitions from the 4f65d1 to the 4f7 electronic configuration of Eu2+ ion. The maximum emission of phosphor corresponds to the europium concentration 7 mol%
