Luminescence Properties of (MxMg1-x)2SiO4:Dy3+, Eu3+ (M=Ca, Sr, Ba)

摘要：

　　A series of phosphor of(MxMg1-x)2SiO4:Dy3+,Eu3+ (M=Ca,Sr,Ba) were synthesized by high temperature solid-state reaction method and studied.The structure and emission spectrum excited by near violet light were investigated.The excitation spectra of single-doped (MxMg1-x)2SiO4:Dy3+ show strong absorption near 322nm,347nm,362nm and 391nm due to 6H15/2→4I9/2,6H15/2→6p5/2,6H15/2→4F7/2,6H15/2→4G11/2 transition of Dy3+.The emission light is at about 469nm,474nm,483nm and 494nm under 391nm UV excitation.In order to obtain white light emission,(MxMg1-x)2SiO4:Dy3+,Eu3+ (M=Ca,Sr,Ba)were prepared to enhance the red light emission.
