Abstract
Sr2MgSiO5:Eu2+phosphors were synthesized through a high temperature solid state reaction method. The phase and luminescence properties of the samples were characterized by X-ray diffraction (XRD) and a luminescence spectrometer. The effects of RE3+ (RE = La, Ce, Pr, Sm, Dy, Ho, Er, and Tm) on the luminescent properties of the samples were studied. The results show that the luminescence spectrum of Sr2MgSiO5:Eu2+ is a broad band composed of two emission peaks, at 460 and at 530 nm under near-ultraviolet excitation. Rare earth ions Re3+ (RE = La, Ce, Pr, Sm, Dy, Ho, Er, and Tm) have great influence on the emission of Sr2MgSiO5:Eu2+ phosphors. The La3+ ion in Sr2MgSiO5:Eu2+ phosphors greatly enhances the emission at 460 and 530 nm.
