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.
