SiO2 and Si(OC2H5)(4) were employed as the raw materials to synthesize blue long afterglow phosphor Sr2MgSi2O7:Eu,Dy via a combustion process with ultrasonic dispersing technique, respectively. The crystallization, particle sizes and luminescence properties of the samples have been investigated systematically by using powder X-ray diffraction, transmission electron microscopy, luminescence spectrophotometer and brightness meter. Compared with the phosphor obtained by employing SiO2 as starting material, the phosphor powder prepared by using Si(OC2H5)4 has purer Sr2MgSi2O7 phase, smaller particle size, and shorter wavelength of main peaks of excitation and emission spectra. Nanoparticles can be obtained by using Si(OC2H5)4 as starting material. The afterglow properties of the phosphors were also studied in this article. (C) 2007 Elsevier Ltd and Techna Group S.r.l.
