摘 要：A series of red phosphors Eu3+-doped MMgP2O7（M=Ca,Sr,Ba） were synthesized by solid-state reaction method.X-ray powder diffraction（XRD） analysis confirmed the formation of pure CaMgP2O7,SrMgP2O7 and BaMgP2O7 phase.Photoluminescence spectra of MMgP2O7（M=Ca,Sr,Ba）:Eu3+ phosphors showed a strong excitation peak at around 400 nm,which was coupled with the characteristic emission（350-400 nm） from UV light-emitting diode.The CaMgP2O7:Eu3+,SrMgP2O7:Eu3+ and BaMgP2O7:Eu3+ phosphors showed strong emission bands peaking at 612,593 and 587 nm,respectively.Due to the difference of the ion sizes between Ba2+（0.142 nm）,Sr2+（0.126 nm）,Ca2+（0.112 nm）,Mg2+（0.072 nm） and Eu3+（0.107 nm）,Eu3+ ions were expected to substitute for different sites in CaMgP2O7,SrMgP2O7 and BaMgP2O7 lattice.
