英文摘要	Lu3-xAl5O12:xCe3+ (LuAG:Ce 3+) green phosphors were synthesized by a two-step solid state reaction method. Morphology and optical properties of the phosphors were studied by adding various fluxes (BaF2, H3BO3, NH 4Cl, NaF), as well as the concentration of different flux materials were optimized for maximum luminescence intensity. X-ray diffraction, scanning electron microscopy and photoluminescence spectra measurement were used to investigate crystal structure, particle morphologies and luminescence properties, respectively. The obtained phosphors with fluxes possessed better particle morphologies than that of the phosphors without fluxes. The particle size distribution and the luminescence intensity of the obtained phosphors were predominantly dependent on the type and concentration of flux materials. The results showed that the maximum luminescence intensities were found with the following order: BaF2 (3 wt%)>NaF (0.5 wt%)>NH4Cl (2 wt%)>H3BO3 (4 wt%)>no flux. ? 2014 Elsevier Ltd and Techna Group S.r.l.
