文摘This paper reports the detailed preparation and phosphorescence properties of Eu2+-activated Ca2ZnSi2O7 phosphors by a modified solid-state reaction.Phase-pure crystalline Ca2ZnSi2O7 is obtained at 600℃,a much lower temperature than by conventional solid-state reaction and the preparation process of Ca2ZnSi2O7 is simple.The obtained phosphors showed three emission peaks at 480,580 and 620 nm,respectively.Auxiliary activator R3+(R=Dy,Nd,Tm) would enhance their luminescent properties.
