Research highlights: → BaMgAl10O17: Eu2+ nanorods were synthesized by sol-gel process. → Luminescent intensity was enhanced by introducing CTAB. → Thermal stability was improved by introducing Mg2+. → The optimum nanorods could be applied in high resolution plasma display panels. - Abstract: BaMgAl10O17:Eu2+ nanorods were synthesized by sol-gel technique, and their luminescent properties were investigated upon the irradiation of vacuum ultraviolet (VUV) light. By introducing surfactant cetyl-tri-methyl-ammonium bromide (CTAB) in sol-gel process and additional Mg2+ in the raw materials, the emission intensity and thermal stability of the nanophosphor were both enhanced. The above improvements made it possible that the nanosized BAM phosphor could be a good alternative for PDP application.
