Abstract:A homogeneous and stoichiometric Sr 3MgSi 2O 8:Eu 2+ (SMSE) phosphor has been prepared by a simple sol-gel Approach. TEM, SEM, XRD and spectrofluorimeter were used to monitor the structure evolution and optical properties of the phosphor. While TEM/SEM image of as-calcinated phosphor disclosed a spherical morphology with average size of 0.5 m. X-ray diffraction (XRD) of the SMSE powder displayed a pure Sr 3MgSi 2O 8 pattern after annealing at 1100 C for 2 h. The luminescence intensity of the sol-gel-derived phosphors is much higher in comparison with that of the solid-state-derived phosphors. ? 2010 SID.
