Abstract:A homogeneous and stoichiometric Sr3MgSi2O 8:Eu2+ (SMSE) phosphor has been prepared by a simple sol-gel Approach. TEM, SEM, XRD and spectrofiuorimeter 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 3MgSi2O8 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.
