Abstract: Nanocrytalline BaMgAl10O17∶Eu (BAM) blue- emitting phosphor for plasma display panel(PDP) application was rapidly prepared by low- temperature combustion synthesis. The results of XRD and TEM analysis show that the sample is monophasic and well- crystallized, in which displace as well as twin crystal do not exist. Moreover, BAM nanocrystals exhibit an ideal spherical morphology with a grain size of about 20 nm. The luminescent property of the BAM phosphor is also measured and analyzed. The emission spectrum of the BAM consists of a wide band with the peak at 450 nm, which corresponds to the transition from the 4f 65d excited state to the 4f 7 ground state of Eu2+ ion. The blue emission is excellently consistent with commission international del′eclairage(CIE) chromaticity and quite suitable for plasma display panels. The phosphors synthesized via combustion method exhibit higher emission intensity than those prepared by solid- state method because high purity and good crystallinity of the phosphors synthesized via a combustion process cause an increase in luminescence efficiency.
