| 中文摘要 | The synthesis and luminescence properties of Zn2SiO4:Mn phosphor layers on spherical silica spheres,i.e.,a kind of core-shell complex phosphor,Zn2SiO4:Mn@SiO2 were described.Firstly,monodisperse silica spheres were obtained via the Stober method by the hydrolysis of tetraethoxysilane(TEOS)Si(OC2H5)4 under base condition (using NH4OH as the catalyst).Secondly,the silica spheres were coated with a Zn2SiO4:Mn phosphor layer by a Pechini sol-gel process.X-ray diffraction(XRD),scanning electron microscope(SEM),energy-dispersive X-ray spectrum(EDS) and photoluminescence(PL) were employed to characterize the resulting complex phosphor.The results comfirm that 1000℃ annealed sample consists of crystalline Zn2SiO4:Mn shells and amorphous SiO2 cores.The phosphor show the green emission of Mn2+ at 521nm corresponding 4T1(4G)-6A1(6S) transition,and the possible luminescence mechanism is proposed. |
