摘要：A homogeneous and stoichiometric BaMgAl10O17:Eu2+ (BAM) phosphor has been prepared by a simple nano-coating process. TEM, SEM, XRD and spectrofluorimeter were used to monitor the structure evolution and optical properties of the phosphor. While TEM/SEM image of the precursor disclosed a spherical core-shell morphology, X-ray diffraction (XRD) of the BAM powder displayed a pure BaMgAl10O17 pattern after annealing at 1300 degrees C for 3 h. The luminescence intensity of the nano-coating-derived phosphors is much higher in comparison with that of the solid-state-derived phosphors. (c) 2007 Elsevier B.V. All rights reserved.
