摘要
A novel bluish green-emitting silicate phosphor, RbBaScSi3O9 : Eu2+, was synthesized by a conventional solid state reaction method. The RbBaScSi3O9 : Eu2+ phosphor can be excited by a near-UV and blue light irradiation and presents a bluish green band centered at 500 nm due to the allowed transition from 4f(6)5d(1) to 4f(7) of Eu2+. The maximum emission peak intensity was obtained at the composition of RbBaScSi3O9 : 10 mol% Eu2+, and the emission intensity was 13% compared with that of the commercial YAG phosphor.
