Abstract

Blue-green emitted barium silicate phosphors, Ba4Si6O16:Eu2+ and Ba5Si8O21:Eu2+, were prepared by a conventional solid-state reaction. In these hosts, the corner-sharing [SiO4] tetrahedral formed a chain framework structure. These silicate phosphors can be efficiently excited by n-UV light, yielding an intense blue-green emission. Under excitation by near UV light, the emission bands are broader than that of the Ba2SiO4:Eu2+ phosphor.
