| Abstract | BaAl12O19:Mn2+ nanoparticles were successfully synthesized by a reverse microemulsion method. The nanoparticles were characterized by transmission electron microscopy, X-ray diffraction and photoluminescence measurements. The results indicate that BaAl12O19:Mn2+ with spherical morphology can be synthesized at 1200 1C, which is about 300 1C lower than that of solid state reaction with size ranging from 40 to 100 nm. Monitored at 515 nm, the excitation spectra of as-prepared BaAl12O19:x Mn2+ (0.1pxp0.5) and bulk BaAl12O19:0.1 Mn2+ are similar. The bands at 130 and 156nm were observed and assigned to the optical absorption of AlO4 and AlO6 groups, respectively. The emission band position of nano-BaAl12O19:0.1 Mn2+ is 6 nm shorter than that of the bulk due to the low symmetry of crystal field near the surface of nano-BaAl12O19:Mn2+. The optimum emission intensity was obtained at x ¼ 0.2 of Mn2+ doping. Furthermore, the decay behaviors of nano-sized and bulk BaAl12O19:0.1 Mn2+ have also been discussed. |
