Morphology control and VUV photoluminescence characteristics of BaMgAl10O17:Eu2+ phosphors

BaMgAl10O17:Eu2+ (BAM) phosphors for plasma display panel application were successfully prepared by a novel solution combustion synthesis method. Morphology control of BAM phosphor particles in the process was attempted by using polyethylene glycol (PEG) as additive. The crystallinity, particle size, morphology and luminescent properties were characterized by XRD, FE-SEM and vacuum ultraviolet (VUV) irradiation derived synchrotron radiation, respectively. It was found that BAM phosphors resulted from PEG additive have nearly spherical morphology, narrow size distribution and strong blue emission under VUV light excitation compared to those without PEG additive.
